Just saw this for the first time. It takes a while to get going doesn't it?
I feel like this could have started later in the piece and spent less time showing how much Andrew was bullied, and worked that in to the flow of the film more. I never really felt bad for Andrew so wasn't too concerned when his long-telegraphed spiral happened (the character's save the cat moment happens too late in the piece when Matt, Steve, and he are already flying gods). Matt was too apathetic to really get behind; he starts cool, shows some low level vulnerability to Casey, and then saves the day.
But it was kind of fun from a what-if perspective. Did anyone else feel like they were channeling the second act of Akira for the entire film?
