One of the better DC animated features, I'd say. Some good fights, some fun character interactions, and a goofy but comic book appropriate story. Also, it might be the only time I've kinda liked Damien Wayne.
And props for the Super Mario and 80s cartoon Krang references.
I thought it was pretty good too. Had the kiddie stuff but not over much.
I enjoyed it, it wasn't to serious but with the TMNT's as part of the story I figured it wouldn't be anyway. That being said, that was a great Shredder in the movie.
