Long story short, I was pleasantly surprised, and very amused.
Despite not being as complex or risky as other Pixar movies, Elementals still manages to entertain with its simple "Romeo and Juliet" plot and beautiful animation.
[Slight Spoiler]
The focus is mostly on the relationship between fire and water people. Earth and wind people get less attention and almost feeling like an afterthought.
If you have young kids or a big Pixar fan in the family, I recommend this movie for a fun weekend event or family movie night.
