Pretty good, but doesn't really compare to 28 Days Later.

Rating: 7/10 (12 May 2007)

Went to see this last night. Pretty good. It's just not the same kind of thing as 28 Days Later. Less of a "smart people getting pulled in to a Lord Of The Flies type situation and human nature takes over" and more of a conventional "stupid people doing stupid things that totally screw up everything." Danny Boyle's protégé did a good job of emulating his directing style, and Boyle directed some of the 2nd unit scenes -- so if you like the feel of the scenes in 28 Days, you should appreciate the new movie. But it's a different writer, and it shows.
At this point, I'm curious about Boyle and (28 Days writer) Alex Garland's sci-fi epic Sunshine -- which seems to playing in every country right now except the US and Canada!!
