Avengers (score: 9)

Avengers understandably cannot go as deep into each character as the heroes' individual films, but Whedon's  script succeed in not single out any hero while telling a fun story that justifies every action sequences. Even if the trashing of New York climax remind me way too much of Transformers 3's trashing of Chicago, Whedon's famous witty dialogues throughout kept everything fresh until the end.
