This movie is only any good if you're a Lego maniac, like me. At the time, I was a Bionicle freak, and grabbed for any Bionicle available at Wal-Mart. Really, if you don't really like Legos, don't waste your time. The animation is decent, but it isn't exactly what you're looking for. If you can actually do CGI, you can see lots of problems. The particle systems were pretty bad. The line delivery was awful. But this movie actually has a little bit to offer. The music is good.
Only get this at the library. Don't spend 20 bucks on a movie just for Lego geeks like I did.
