I went with the Avengers though for story it is kind of unfair given that the Avengers is not only an adaptation but also technically a sequel to many popular movies so for investment in the story it has a greater build up. That being said Pacific Rim had it's share of great over the top action moments that got me more hype but overall their was less action scenes in the movie just really really good action scenes (for spectacle). Pacific Rim also suffered from a loss of spectacle when you see it on a home theater system instead of how I experienced it which was in IMAX 3D where as the Avengers is more built around character development based action and its impact on the universe over spectacle in height of the things battling each other.
