Okay, I had to write something here because the only other reviews here gave it 1/10 and honestly, I didn't think it was THAT bad. It's not exactly good, but it's really not that bad.
The script and dialogue are terrible and all over the place, but it's so bad that it's actually kind of funny if you don't take it too seriously. I actually liked a lot of the animation. I've seen much worse. It's better than the animation in Speed Racer. Maybe that's not saying much, but you could tell that in parts of this, some serious work was put into it.
This thing has a little bit of everything, ripping off everything from Voltron to Tron to Dracula and so much more I lost count. It was fun to keep watching and see what they were going to rip off next, whether it made any sense to the story or not. I was laughing my ass off!
If you've got an hour or so to kill, you could do worse.
5/10 is probably too generous, but 1/10 is too harsh, in my opinion.
