Men In Black 3 (score: 8.5)

Instead of being "another day another alien" story like the second one, Men in Black 3's self contained time-travel case feature enough Men in Black style weirdness, including Josh Brolin's amazing role as a younger and more chilled version of agent K, that help elevate the film from being more than just another Men in Black episode.

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.
