Assault on Arkham is the prequel to Batman: Arkham Asylum. So it hols a very niche' place in the "Arkhamvers". Which is a term I didn't even know existed. It refers to the media that is related to the Arkham video games. So far, this is the only movie in that universe, and while it's not as great as it could have been, it definitely isn't as bad as it could have been either. The voice cast definitely helps elevate this movie. The story is all over the place, and then animation is a little cheap, but overall it's fun.
