For those too lazy to click that site, here is the trailer from their webpage.
I suspect that this will be shown on TV at a later date in 3 episodes for the movie was split into three segments each with identical opening and closing credits. There were far too many villains running around and it made it rather confusing at times although the fight scenes were excellent. Some very cool monsters (a manticore, a succubus, etc.), great animation, a good score are some of the highlights.
I picked up a couple of Clear Files (of course), I like the adorable little Devilman and 009. What cuties!
Here are some clips from the movie:
Unfortunately this was on a limited release so I don't know when you'll get a chance to see it. Seek it out though, it's worth it.
