I've just pre-ordered Gravity on blu-ray....its being released in the UK on 3rd March.
I never saw the film at the cinema (I haven't been for years) but have seen various clips and it certainly looks impressive. Apparently its won several awards at this years BAFTA's.
I quite like George Clooney (he was brilliant in that other sci-fi epic, Solaris), so it will be interesting to see him return to outer space again.
I really enjoyed it. But then I'm quite a fan of slow moving sci-fi films (Solaris, Moon, 2001, Gattaca, Sunshine etc) so I wouldn't exactly recommend it to someone who likes the Star Wars films for example.
