I just saw the movie a week or 2 ago and i have to say they did a really good job cramming most of the stuff in that movie.
There was only one thing that annoyed me bigtime and that was the colorgrading it was truly horrific.
It was very yellowish and it smudged the entire movie.

I hope that they shot that colorgrader , but seriously i liked the other movies so much aside from the story, because they integrated all the effects in the movie and quite believeable at that, now it looks like they are integrating the movie in the effects .
