I loved Memento and wanted to like this film. I kind of enjoyed it while watching, but the more I reflected on it, I realize I didn't.
Possible spoilers:
I know it's an old convention, but there was something very artificial about the characters constantly explaining what was going on to the other characters, strictly for the audience's benefit.
The whole thing about not seeing the kids' faces, until the very end of the movie, seemed like a pasted-in, manipulative device that didn't serve the narrative, attempting to elicit an emotional response that wasn't earned.
The sets were interesting on some level, but they kind of came off like, "Wow, we have gazillions to spend and some great software. What can we do?"
Hans Zimmer's pompous score was just awful. It sounded like a parody. It pushed me outside of the film rather than drawing me in.
Still, there were some good elements. The premise was interesting, even if they didn't quite pull it off. I thought Leonardo DiCaprio did a good job considering what he had to work with.
It probably provides a more intense experience in the theatre than on DVD, but I'm not sure I could recommend people paying top dollar to see it.
