All i found in that was great action and humour, not much else.
X2 has much more well rounded elements on offer.
Emotion: Jeans Death, Bobby leaving his family
Character development: Nightcrawler/Storm religious relationship, Jean/Scott/Logan love triangle, Bobby/his family, Pyro's defection.
Character Motivation: Wolverine moving on from being a loner to a team member, Bobby leaving his old family to fully embrace his new family, Stryker's reasoning behind his hatred on Mutantkind
Humour: Mansion & Blackbird scenes
Action: Opening with Nightcrawler, Deathstryke fight, Magneto's escape
While Avengers was fun, it was also empty of depth. Loki never showed any reasons for wanting to take over Earth, he wasn't a big enough threat to assemble a team for, he just was written to be the bad guy for the sake of the need for a bad guy. Cap never mourned Peggy or questioned if he should work for SHIELD, Thor never went to see Jane. Colousons death felt forced just to get them working together, it spent a good portion with filler material like 'what was Loki's play' being asked over ad over and about half an hour fixing the helicarrier.
In short it didn't have a story, just a series of scenes. The foundation seemed like simple 'wouldn't it be cool to see these characters on the screen together'. For me that's not enough to be called the best of anything. The first Cap, IM and Thor are better complete films as they tell a story, the characters develop & change throughout the course of the film.
It is a fun movie to be sure, a feast for the eyes and adrenal gland but doesn't have the substance that most of other superhero movies have.
