Great autopsy!
I love Alex Garland and Danny Boyle, taken individually or together. The Beach remains one of my all-time favorite novels and I think Trainspotting, Millions, and Shallow Grave are all remarkable films. 28 Days Later, their first union, I absolutely adore.
So I really wanted to love this movie. And I found there was a lot to like about it. But that last 25 minutes felt...wrong. Pinbacker seemed too much of a supervillain.
The more I think about it, the more I can justify it. There's a nice mirror story there between Icarus I and II. And I imagine Al's right - that I could watch it a 2nd time (which I probably will one day) and it will work better. But I remember Sullydog reviewing this last year, and saying something along the lines of worth seeing, if only to see how close they came to making a great film, and then completely blowing the last act.
