Grisly Dexter still cuts it as a killer show Michael C. Hall as Dexter. As far as serial killers go, Dexter is a top bloke. He chooses his targets wisely, topping only those whose crimes he believes to be particularly heinous, and he's very good at cleaning up after himself. Why the bloke in the local shop where he buys the endless rolls of blood-catching plastic hasn't twigged is beyond me. Whichever way you look at it, Dexter is a ruthless, cruel killer and the audience is asked to empathise with him. He has a "dark passenger" - the urge to kill - after a childhood experience with murder. That was six series ago, and he has retained the inner monster, but now begins to wonder what message he has to pass on to his son. Surely keeping a nice set of knives to carve up bad guys is poor parental advice. I love Dexter (Eleven, 9.30pm), while steadfastly opposing its leading man's stabby-stabby approach to relationships. The problem is, Dexter is not so fond of Dexter, and actor Michael C. Hall tells us so directly in his narration. It's a world-weary voice, running the gamut of emotions from A to whatever comes between A and B. A and a half? A one-off viewing of Dexter may leave you unsatisfied. It is far better to slip totally into this Miami cop-shop world, where Dexter is the blood-spatter pattern analyst. Nice work if you can get it. Recent series have seen him matching blood spatter efforts with the likes of John Lithgow as the Trinity Killer, and this series has Edward James Olmos as a religious kook creating a deathly biblical-themed tableaux. The eighth and final season of Dexter will screen on Showtime in June. Still with killers, if blood-spatter pattern analyst is an odd job, what about Python Hunters (One, 7.30pm)? For those of us who spend our lives avoiding snakes, this is loony tunes. But they do the job with such relish and in Monday's Deadly Down Under, the quest to lay hands on the most deadly creatures on Earth reaches Australia. "We're gonna get our hands on some highly venomous sea snakes," says one hunter at the top, as if it's an attractive notion. As a bonus, there's a good chance they'll run into some box jellyfish, which can kill quicker than anything that's not carrying a gun. This is gung-ho boys stuff featuring adventure scientists who think they're Indiana Jones ... without his fear of snakes. David Attenborough has held snakes, sat next to bears, felt the spray from a nearby whale's blowhole and so much more during his wonderful career. In 60 Years In The Wild (Ten, 8.30pm) the leader of the pack tracks the changes in filmmaking, science and the environment during this time.
