Watched this yesterday and really enjoyed it.
Found it gripping and quite a few unexpected moments.
It's not so much about great acting or great script.......but what a storyline for edge of the seat entertainment.
I can easily understand why 3D viewing would be recommended with this film....would be wonderful, but still a good enjoyment on my standard HD telly.
I enjoy sci-fi and especially space drama.
For me this is bang up-to-date and believable.
Besides which there's Sandra Bullock (oh and George Clooney)
