There are cartoons created for adults, and cartoons intended for children. The Triplets of Belleville falls into the the former category, and though sometimes we don't love such films, we really enjoyed this one.
The movie includes an incredible dog, which we have an incredible soft-spot for. Also, an amazing singing trio, many frogs, and a buff-legged cyclist.
Quick vote: This short flick is quirky and original. We recommend it!
