Some quick thoughts...
This is was actually pretty fun. It did border very close to being too silly but it always managed to time itself to keep serious drama dialogue with tongue in cheek sarcasm.
Visually it was impressive but it could still have been a little more in depth. The new role of the Hulk was fresh and interesting but it didn’t quite present as much as it could have.
It did occur to me though that these films could spend a bit more time on scenery landscape shots, setting up a bit more tension before a sudden confrontation.
