Sorry, but no
17 November 2009 | by Jeremy-93See all my reviews

I wanted to like this, I really did. The BBC were trailing it as just the kind of episode I wanted to see - taut, scary, grown-up, sombre, intelligent sf. And if you'd cut it by about half, re-edited the remainder, and come up with some new stuff, you'd hit the jackpot. I like David Tennant's Doctor more and more, and will miss him in the role - he has a near-perfect combination of gravitas and impatience, and can shift in a moment from excessively cheerful to deadly serious to alarmingly peculiar, like no-one since Tom Baker. And I like any episode that doesn't turn on conventional sexual tension imported from Buffy. Trouble is, the script just wasn't good enough. Scenes went on and on, with diminishing returns. Doomy, adolescent self-indulgence got substituted for seriousness. Scary gave way to vaguely embarrassing. I started feeling sorry for Lindsay Duncan without even being sure whether she was feeling sorry for herself or had got sucked into the corporate self-regard of a show that badly needs to be stripped back to basics. I prefer to be optimistic that Steven Moffat is the man for the job, given the very high quality of the eps he's written. Lots of hard work went into 'The Waters of Mars', but the writing is hollow.
