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.

Not only spectacularly well made but frequently very funny.

David Stratton
The Australian
Monsters vs Aliens is skilfully animated and spasmodically funny, but you get the impression the film's seven (!) writers ran out of ideas two-thirds of the way through.

Engagingly nerdy movie in-jokes are clearly a step in the right direction for DreamWorks after the rather crass and bombastic approach of the Shrek movies.

Although the voices were well-chosen, the action scenes set on Golden Gate Bridge in San Francisco have, without doubt, their particular charm... the movie in general leaves a lot to be desired. [Full review in Spanish]

Audience Reviews for Monsters vs. Aliens

Mar 29, 2016

A ton of fun, Monsters vs. Aliens is both a hilarious parody and homage to the monster movies of old while also giving us a lighthearted and enjoyable tale about acceptance - even if it appeals more to kids then adults.

It returns the idea for something never been done a long time ago, but clearly it wasn't what I wanted but it still works anyways.

DreamWorks Animation presents the ultimate no-holds-barred contest in Monsters vs. Aliens. The story follows a group of monsters hidden away at a top secret military base who get a chance at freedom when the U.S. government calls upon them to stop a giant alien robot that's attacking San Francisco. With the voice talents of Reese Witherspoon, Will Arnett, Seth Rogen, and Kiefer Sutherland, the cast is pretty impressive. However, the characters are a little cartoony and played more for laughs than storytelling. But this works for the style of comedy that the film is going for, and the jokes are rather good; mixing parody and slapstick quite well. Though it tends to be a little silly at times, Monsters vs. Aliens is a brawl not to be missed.

As exciting as the 1st monsters animation plus a wide spectrum of celebrity voices.
