If I watch a movie for the second time, it's either because it's a classic and means a lot to me, or when I'm watching with my kids something they haven't seen yet Well, I guess if you managed to watch it all the way through, it wasn't exactly a snooze fest )
Didn't mean to imply this is low brow entertainment. If you're a serious sci-fi fan you'll like this, especially if you find Dark Forest theory an interesting concept. Doesn't quite follow the book trilogy to the letter, but does an adequate job.
