Good way to waste your money.
Okay, I didn't get it. The kids were enthralled by it and that was worth it, but it's no Turbo or Planes. Nothing in there for adults at all and at point the movie actually made me feel queazy with the swirling colours. Also the impromptu singing/songs just seemed weird...
If your kids love moshi monsters then I would say pop your iPhone in your ears and endure it, otherwise stay clear.
