When a meteor full of space gunk transforms Susan Murphy (Reese Witherspoon) into a giant, the government renames her Ginormica and confines her to a secret compound with other monsters, like bug-headed Dr. Cockroach (Hugh Laurie). When an extraterrestrial robot lands on Earth and begins a rampage, Gen. W.R. Monger persuades the president to send Ginormica and her fellow monsters to battle the machine and save the planet.

Critics Consensus

Though it doesn't approach the depth of the best animated films, Monsters Vs. Aliens has enough humor and special effects to entertain moviegoers of all ages.

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.

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

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.

The robot in that movie gives me inspiration for my cartoon. The husky metallic robot arms, the stumpy feet, and the one eye.

Great cast and wholesome. Flat story but we aren’t supposed to expect the Titanic from DreamWorks
