The movie was good. I hated the way it ended and felt like it was completely disconnected from the other movie endings. Every movie before has ended with the three kids together. Not this one. I saw it in IMAX. I felt that experience was ok, but not really a huge change. If you have a extra couple of bucks, it is worth it, but not necessary. All in all, a good movie. Lots and lots of suspense. They really did a great job at making you feel as though the enemies were right there. A good movie! Cannot wait for the finale!
