My personal favorite movie of all time. It has everything one might want from a film, action, drama, emotional moments. I never re-watch movies, but I've re-watched this four times and have cried each time. I understood the story from the first time around, but I can kind of see why people might be confused. Also if you're photosensitive, this movie has many flashing lights and imagery. I'd be careful if you have something along those lines. Otherwise, go rent it right now and give it a watch!
