Things that I liked:
- The idea of everyone failing to sleep and the subsequent effects on the mind etc.
Things I didn't like:
- The fact that there's no real exploration in the beginning - one night of no sleep wouldn't immediately cause worldwide panic, I would have expected that level of panic to be the case after at least 2 nights.
- The middle portion of the movie was boring.
- The little girl randomly asking her brother "did you, like, DO it?" Laughable. Didn't make sense in the context, and didn't add anything to the story.
- The solution doesn't make sense. I won't go into why as that would be spoiling.
