User Reviews

Great Animated Film. Don't listen to the naysayers.
23 July 2010 | by (United States) – See all my reviews

I honestly don't know what some of these people who've reviewed this film were expecting.

Sure, it's called "Monsters Vs. Aliens." No, that DOES NOT mean that it HAS to be about five thousand monsters fighting five thousand aliens. You people watch too much Predator vs. Aliens.

What this was was a story about one girl, what happens to her and the challenges she faces.

And it's funny. Very funny, in an adult, dry and quirky way. It's not trying to be generic, which seems to be what some reviewers want. It's not trying to be a spectacle, like other reviewers expected it to be.

It's a well told comedy about this girl Susan.

My three year old has seen this movie somewhere in the range of 40 times. I've had to sit through it at least half of that and, quite honestly, it doesn't grow old for me like A Bug's Life or something in that vein might.

Too many people with too specific expectations - and no concept of what's good. Must be why Transformers made so much money.
