My son and I ordered our tickets almost two weeks in advance. After an anxious two week wait, I can honestly say that we were NOT disappointed. My son rarely will sit through an entire movie, but he was glued to the screen for the full length of the film.
As an old-school TF fan, myself, there were a few liberties taken with the characters that I could have done without; but it did not detract from the experience so much as to make me dislike the movie.
The special effects, pacing, casting, and character portrayals were all awesome. I'm almost tempted to go watch it again and can guarantee that I will buy it when it comes out on DVD/Blu Ray.
