Well, I hate to say, I had gotten a one word spoiler (aliens) before I had the chance to watch it, so it wasn't a surprise, but I'm kinda glad it wasn't because I think I would have hated to go from the very human thriller inside the shelter to a science fiction War of the Worlds type action without any warning. I braced myself for the aliens being a bad move. It still felt a little War of the Worlds-y and I half expected Tom Cruise to come running out of somewhere, but I liked that her character really followed through with her development, and her decision at the end to go toward the war instead of running away felt like it made the story complete and cohesive instead of two, smashed-together arcs.
