When I watched the movie the first time, I was still a kid and thought it was a little boring, but now, rewatching it I can see how great of a movie it is, the beginning of the movie makes you feel that everything is in danger, how dangerous the world has become and it gave me chills, after that, the movie slows down a little but it gives us very significant interactions between the characters and thats where the interesting part is, its very subtle, but interesting and deep, and it also gives the characters time to think what they should do and the next step they should take. Its amazing.
