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.

4/10

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.

2/4

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

Brilliant! ("doesn't approach the depth of the best animated films") 🙄 ... Amazing cast all shine in their voiced characters. Very well written and directed. Great cinematography and visuals, stunning pictography. Lots of weirdness, charm, allure, drama, dilemma, suspense, twists, emotion, intrigue sharp wit, hilarious at times and filled with "extraterrestrial-ness" 😜 Fast paced and mind bending as it should be. Fantastical, whimsical and very entertaining

This was a nice surprise! Did not expect much from it and came out thoroughly impressed! From the animation to the voice acting to the fun ideas it plays around with classic monster find including Gordon’s Godzilla and Mothra. It rocks.
