Wonderful summertime treat (even though it's still spring) ...
30 March 2009 | by (United States) – See all my reviews

If you're going to see this movie, make sure it's the 3D version - not all showings are in 3D. If you have the opportunity to see it in IMAX - it's definitely a 'bigger' treat ... but FWIW, know this: it was "converted" to IMAX from normal print - not created in the IMAX format.

OK - that said, the movie IS worth seeing. I'd say it was somewhere between "really good" and great. It's a fun story with fast pacing, entertaining characters and nice 3D effects.

It's basically about a group of 5 likable "monsters" that are pitted up against an alien attack. The main character is a new "monster" - Ginormica. She's a young lady that was recently hit by a meteorite with a special composition ... one that made her grow to gigantic size.

It's a fun story told in an imaginative way. The visuals are very nicely done - the backgrounds, characters and scope of detail are great. The movie also moves along at brisk pace - something that grabs your attention is always happening (this makes it work well for kids in the audience). Add to that the fun and oddball personalities of the monster characters and you have a winning combination.

The 3D effects were good, although like most other mainstream animated movies - they start out strong and then get recessed into background. Still - make sure you see it in 3D! You'll be missing part of the key experience offered by the movie if you don't.

All in all, this is a fun movie for adults as well as kids. It's kind of a summer movie that you get to watch in the spring. Grab some popcorn and check out this flick!
