Monsters Vs. Aliens has plenty of lively animation and a handful of solid jokes. It is not of a caliber of most of the Pixar films, but, at times, it comes close.

AniMat's Review (YouTube)

Monsters vs. Aliens attempted to be a tribute to those classic sci-fi/horror movies, but it feels more like a mainstream mess than have any of that campy charm.

Rated: 4/10

Deep Focus Review

Whereas animation should have limitless potential, particularly with a concept like the one in Monsters vs. Aliens, this film squanders its prospects on mundane storytelling

Rated: 2/4

A creative medium for DreamWorks. The 2 species being monsters & aliens are comparable but different. Finally, you could see them crossover. The cast will be memorable: Reese Witherspoon being Susan/Ginormica was random but would be a suitable role; Seth Rogen is B.O.B who is real funny; Will Arnett has that perfect voice for somebody like Link; Hugh Laurie is charming & witty being Dr Cockroach; finally, you got it right with Steohen Colbert as President Hathaway (would you rather have him as president) when he discusses politics with his stand-ups. There are true moment like Hathaway playing "Axel F" on the keyboard & Gallaxhar's backstop kept being interrupted although he continues regardlessly. Ever noticed the references to old skool monster movies? The movie can be meaningful, Susan/Ginormica felt like nothing as a giantess but her leads to her saving our world from these aliens with the other little fellas. B.O.B was a monster without a brain but he was not always idiot because he said had an idea & it was true. This movie was set up for me.

Monsters vs. Aliens (2009) is a film that has a very cheesy and exaggerated story, but its characters have a silly humor with a very fun combination. This story is not well-crafted but it manages to deliver good fun and entertainment.
