"Freaks of Nature" proves a lifeless combination of alien invasion saga, zombie thriller, vampire romance and high-school drama.

...a thoroughly abhorrent endeavor that squanders its appealing setup and roster of talented performers.

This horror-comedy starts off with a good idea -- i.e. monsters learning to work together -- but doesn't take it very far. The likable characters and a few laughs are the only worthwhile things in it.

There's a whole lot of arid downtime in between the ostensibly colorful set pieces, and on the whole the movie seems like it was edited with a blender.
