I watched The Box and Atonement this weekend.
The Box started off fairly well. Unfortunately, they then took it in a direction that was confusing, with huge plot gaps, etc. It felt like I'd skipped over certain chapters on the dvd. The last half of the movie really stunk, to the point where I'd give this one a thumbs down.
Atonement was filmed well, was well-acted, had an interesting enough story... It's just not a story I liked very much. The world doesn't always have a happy ending, but I'd like my love stories to.
