This is the first time I've watched all 3 OVAs uncut versus the theatrical version, and it's just as much of an epic experience, maybe even more-so as it fleshes-out (pun intended?) a lot of the characters and the storyline. Don't ask me how, as I can't remember, but I got a copy of the theatrical version on VHS as a teenager in the mid-'90s and I've always loved it. Imagine something like Demon City Shinjuku, but on steroids and lots of amphetamines. I'm not a fan of 95% of hentai, and I honestly hesitate to even call this that. Yes, it's full of sexand tentacles, but the narrative is on such a grandiose scale that I feel it transcends the stereotypes that the hentai genre generally invokes. If these were the standards that the genre held over the years, everyone would be better off.
The characters, especially Amano, are all pretty memorable, the action scenes are killer, and anyone into extreme horror and gore will find a lot to like here. The animation is very good too; this isn't some made-on-the-cheap affair. I can understand how some can't see past the more exploitative elements on display, but for better or worse, this created a whole genre in anime, and it should be respected for that. This is pure excess at the highest level, and it's cool as fuck for my money.
