the problem with BBC be that they tend to price everything into the realm of ridiculous . any fan of  Rome - The complete First season  it be still annoying . and while  doctor who - the complete First Series  First off , we have some solid episode to establish David Tenant . the Xmas Invasion be one of those `` Doctor who can not deal with he regeneration '' story that start with castravolva and the writer keep write . I suppose we can not ask for Tom Baker to jump up and start fight big robot and push Brigidier around , but I do miss the day when the doctor could just be the doctor . still , there be a joy when David Tennant finally wake up out of he coma and take on the alien . it be similar to the joy experience this season when the doctor shed he scared John Smith persona and the alien narrator explain that the whole flee thing be a way for the doctor to be kind . the first few episode do establish the doctor and David Tennant . he be both less dark and more earnest in this season . there be a strain of sorrow go through most of these storyline as you be almost weep for the evil `` last human '' in the hospital storyline and `` the Girl in the Fireplace '' be gear towards break you heart . the sad thing be that I know I 'll hate  Tristan and Isolde -lrb- Widescreen Edition -rrb-  however , tedium set in just after the Cybermen make they appearance as the alternate universe cyberman -lrb- so what happen to the original version ? are they all go ? never explain . -rrb- with a endless series of `` Rose be probably gonna die '' bit , and lackluster story -lrb- the demon planet one bore I . the `` fear she '' one be bad , probably not as bad as most people say but still pretty bad -rrb- the series roll into a really cool two-parter that do not make up for the second half be so dull up until then . if you can buy this for less than the $ 100 ask price -lrb- $ 50 should be the max you pay for a 12-part dvd set . you can get 22 episode of  how I Met you mother - season 1  and that show be much more consistent -rrb- buy it . else wait . the third season be a definite improvement . and while you be at it , pick up a copy of  Teddy Bear Cannibal Massacre
