I wasn't expecting much from 28 Weeks Later - I'm in the minority who thought 28 Days Later was a pretty weak movie. Okay, the first half was good and the second half was nonsense but we're not talking about that movie we're talking about the sequel.
It was pretty cool, I enjoyed it and would recommend it to a fellow horror fan. Don't expect much from it and you'll be fine. Robert Carlyle is Robert Carlyle - though it's difficult not to make Ravenous jokes during his screen time. Everyone else is fine. It doesn't matter because this is one of those movie where you're just waiting for whatever bad thing to happen to them. Personally I like that. The writing was fine, nothing fancy. I did have a problem with the damned shaky-cam that plagues movies now. I don't care if it represents frenetic blah, blah, blah. I want to savor my gore and feel like I've been thrown in a strobe-lit blood filled dryer.
The gore factor was perfectly reasonable...what gore could be seen through the shaky-cam and lighting effects - one section of the movie was shown through a night scope.
All in all worth seeing for a matinee.
