Fairly basic anime material. High on fantasy and action, sporting a large and varied cast of characters, each with their own capabilities (and sidekicks). Like most of these films you may miss some of the finer details when you haven't seen the series or read the mangas before, but it's hardly essential to follow what's going on.
Zash is eying the Dragon Cry, an ancient artifact that may help him destroy the world. A troupe of magicians isn't too happy with that prospect and will do everything in their power to stop him. Cue a series of increasingly destructive fights, but some basic fantasy lore thrown in between.
The art style is a bit crude and the animation certainly isn't up to feature film level, then again that's no surprise for these franchise-based feature-length films. It's a step up from TV anime and that's enough to please the fans. The fight sequences are quite fun and the film doesn't take itself too seriously, but if you're used to watching fantasy anime there's very little here that sets it apart from its peers. Decent fun, but not that remarkable.
