Very late to the game on this one, but it was worth seeing. What a fantastic summer movie that brought back that nostalgic 'feel' of summer movies having nothing to do with the period piece of the movie, but just that great 'summer blockbuster' movie feel to it that had more to do with characters and less than the actual event. I can't remember where I read it, but some filmmaker said they liked to make movies where the event was secondary to the characters (anyone remember this?) so if they dropped these characters on a boat with sea monster, or in an office building with the power out, it didn't matter, the audience would still be glued to the screen.
I got that feeling from this movie. If the train wreck/alien side never came in, i'd still be interested in what happened to them. That 'rehearsal' scene by the train station was absolutely perfect! JJ killed it and brought together a great cast, not to mention Coach from FNL!
