Series one be a tacky , self-mocking soap opera set on Earth with lot of trademark from `` Doctor who '' insert just so the series title could be validate . but while series 1 have its problem , it do have a few worthy moment too . so , how do series 2 compare ? Series two do feel more like ` traditional , classic who ' , especially compare to series 1 . there be a few issue -lrb- just about all of it be earth-based again -rrb- , but all and all it be definitely a tremendous improvement . David Tennant be a refreshing change from the do-nothing Christopher Eccleston . from the wacky to the serious , and from be pro-active and right down to the costume , improvement be all over the place . the overall quality of series two 's episode be definitely sporadic . Series 1 have a similar feel with all of its story , even if the story themselves be lacklustre at best . season two go all over the place in tone and intellectual quality , and despite its clunker be definitely worth the different format -lrb- and actor ! -rrb- indeed , the fact Tennant argue for the character 's name in the end credit to be rename to `` the doctor '' be inspiring . rate on a 4 star basis , 4 be best and 0 be worst : the CHRISTMAS INVASION \* \* 1\/2 the new doctor spend most of the episode in a coma , leave Rose and Mickey to figure out what be up with a bunch of mysterious and deadly Christmas figure and decoration . the only saving grace here be Tennant 's performance , and he be keep to the side for most of it . still , he presence give we hope ... NEW EARTH 1\/2 think we 'll finally get a story set on another planet ? not quite . the replacement for Earth be still call Earth . the whole thing feel like a throwback to Eccleston 's era , right down to body function joke and sexual innuendo -- mindless fluff that be not `` Doctor who '' . this one nearly have I call it quit ... glad I keep on . tooth and claw \* \* \* 1\/2 Queen Victoria , werewolf , odd karate monk ... everything about this be rather good . but something call a Torchwood ? Hmmm ... SCHOOL REUNION \* \* \* anthony Stuart Head steal the show as the villain . it also add some new depth into Mickey . it also bring back Sarah Jane and K9 . my problem with this one be , Sarah Jane be make out to be a ex-lover of the doctor . -lrb- even Mickey state a obvious comment and we be grateful it be not the doctor who say it . -rrb- it be get a lot of great moment -lrb- and in way be what `` Logopolis '' should have be -rrb- , but the bad moment -lrb- involve the verbal sparring between Sarah Jane and Rose -rrb- be cringe . still , all thing consider , it be worth 3 out of 4 . the girl in the fireplace \* \* \* 1\/2 another winner , yet with another drunken excuse to thrust in more sexuality . this time , it be the Doctor himself go after a lady . everything else about this story be great ... then consider the writer of it write the british comedy `` coupling '' and it all make sense as to why the Doctor have to have a sex life . sigh ... why ??? why continue to humanize a alien character for pointless rating ? on the flip side , the ship itself be a inverse of a Cyberman : human organ operate a machine mind . that be way-cool . but the sexual flippancy that be prevalent in the new series in general , why why why ? rise of the CYBERMEN \* \* \* a interesting twist on the re-invention of the Cybermen : a parallel dimension . -lrb- could this parallel Earth be Mondas , the Cybermens ' home world in we universe ? -rrb- we also get the big revelation the TARDIS be organic . -lrb- that be great if the idea of organic technology have not be develop by any number of sci-fi author in the past , include `` Doctor who '' back in 1971 with `` the Claws of Axos '' ! -rrb- the cliffhanger be decent too ... but this one be actually decent . the age of STEEL \* \* 1\/2 Mickey be still great . unfortunately , that be about it . the sonic screwdriver , which have be misuse and overuse in the past , be really OTT in this episode as , amongst other thing , it distract a whole regimen of Cybermen . we also do not need the 59th reminder this be not `` we '' Earth therefore it be not `` we '' Jackie and Pete . the cliffhanger resolution be paltry ... there be some redeeming scene , such as get to empathize with a convert human ... but it be not a perfect resolution . and parallel technology seem quite compatible despite they universe be much more advanced . still , if you do not think about plot hole , change motive , or bad idea in general , this story -lrb- along with most of they -rrb- would all be 4 out of 4 star . also , the new Cybermen costume be not all that great either . sci-fi fan will recognize it as a amalgamation of c3po -lrb- star war -rrb- with melkur -lrb- from the Doctor who story ` the keeper of traken ' -rrb- the idiot 's LANTERN \* \* \* not the best explain , but definitely a creepy and interesting idea regard technology consuming people ' life . -lrb- there be two theme in this series : 1 be Torchwood , which seem force at time . the 2nd be the integration of technology into people ' life , usually for bad effect . this 2nd one be far more interesting and worthy , and the metaphor use in ` the idiot 's Lantern ' be quite good indeed ... -rrb- the impossible planet \* \* \* 1\/2 hmmm . should be a classic . but why be not it ? the fear factor be there , many moment that could have end up as hokey joke be play straight ... but there be no depth to the plot . not even little hint of intellectual depth . nothing to think about , it be just be spoon out to viewer . but it be tense , gripping , and worthy ... but it be a tease . the first time we be away from Earth and there be no alien civilization . just more bogeymonster . the SATAN PIT \* \* \* 1\/2 premonition and resolution . indeed , this conclusion to `` the impossible planet '' be very good indeed , and while the beast be too synonymous with a particular religion , it be venerable . love & MONSTERS ___ why ? it be a parody of who fan , but at least it be parody the new series rather than the classic one . some bit do work , but other be awful . I like the idea of the monster , but they have to go overboard with the crass crudeness and bodily function joke , of which series 2 have be mostly devoid of -- up until now . oh well , I should not have have high hope . -lrb- the writer must be a fan of fox cartoon show ... -rrb- I will not bother to mention the final gag scene at the end . all I 'll say be `` there be a literal meaning to that '' . it redefine low . fear her \* \* \* Hmmm . it seem to be a knock-off of a potential `` Sapphire and Steel '' story . -lrb- or for Americans , it be rather like a episode of `` the X-Files '' . -rrb- the trouble be , the story lose its way at the 35 minute mark and never recover . as usual , the more interesting point be not explain . it be a real mixed bag , but the good point -lrb- e.g. the doctor be trap -rrb- make up for it . the lead-in to the next story be also great at the time . army of ghost \* \* \* \* no more silly reference , Torchwood be reveal . smooth . not quite the same theme as `` bad Wolf '' -lrb- for `` bad Wolf '' , Rose create it but the circumstance be implausible -rrb- , but it be not as loosely shrug off either -lrb- we have no idea how Torchwood would be define ... or how it could exist without UNIT know about it , but that be fair too -rrb- . this be Russell t Davies ' best who story of they all . it be taut , gripping , have some intelligence behind it -lrb- though I be hope it would be more than parallel universe cyberman wander into ours -rrb- , and then there be that cliffhanger that nobody expect -- the return of Daleks . doomsday \* okay , let 's turn the whole affair into a parody of a self-mockery . apart from the initial Dalek\/Cybermen spat , there be nothing worthy here . even rtd can not decide if the Genesis Ark be Dalek or Time Lord technology and merrily mix it up as he go along . worse , have be tell 5,000 time that he be not we Pete and not we Jackie , the doctor seem intent on get Rose to stay with they . and for all the maudlin drivel over Rose say she be die , she be also suggest she be not alive until she meet the doctor . this mean she be only 2 . Hmmm , sound about right ... Billie Piper be a great actress , but Rose be always a huge annoyance when not be a bland one . -rrb- so much plot potential be throw out by empty excuse , and for the big build-up of Rose 's death of fight a big foe , this be one real cheat . and it be a real shame ; I be expect so much more from a terrific build-up . I be look forward to series 3 . all in all , the improvement far outweight the silly quibble that the production team and writer can not seem to wholly divorce themselves from , but series 2 be a massive improvement .
