Yep, the plot line surprised me too but I also enjoyed the film. It did remind me of the original three more than the prequels. Saw it at a local MJR Theater, 2D with Atmos, the film was supposed to be in Atmos but I did not hear anything exceptional. Not that it didn't sound great, it did, just nothing stood out. Really appreciated that the volume was reasonable, no ear ringing when I left the Theater. They did play a couple of Atmos Demo tracks. These tracks definitely let you hear the audio potential of Atmos.
My 2 cents, Jeff
