Utterly horrible. There is literally no feature of this anime that does not suck: bad art (which looks like something out of a 70s Hanna-Barbera Super Friends spin-off), bad animation (it's choppy and stilted), bad sound effects (the Boss Monster at the end is *literally* some guy going "Rawr"), bad voice acting (the allegedly teenage heroine sounds like a 35-year-old prostitute with a mouthful of gum), and a story that is not merely unoriginal, but also just plain stupid.
And I don't mean normal "unbelievable" stupid, or the kind of "silly" stupid that's actually sort of funny. I mean serious, hardcore, brain-damage-inducing STUPID -- the kind of stupid that makes you just stare at the screen blankly, wondering whether it's a joke, because you can't believe it could possibly BE so stupid.
It was SO bad that it actually made me angry. I want those seven minutes of my life back.
If you're reading this page trying to figure out whether this anime is worth watching, please heed my warning: Do NOT waste your time on this garbage. You will only regret it.
