The Humanoid is stupid, pure and simple. But really, that is what makes this OVA fun. I am not ashamed in declaring my love for campy/bad entertainment. This one hits all the things that make them fun to watch. A complex, indecipherable storyline, that has no context or logical progression. Animation that is sub-par and overly dramatic. The sound is delightfully bad--hokey music, uninspired voice acting, and the required action sequence paired with a love song. The characters are pretty forgettable and don't really develop at all. There was some weird love triangle going on, with the man only realizing it at the last second, and the woman oblivious to it, but none of it really made any impact.
What was the purpose of the titular character? Was she capable of love or human emotion? Who were the bad guys and why did they do what they did? The Humanoid tries to answer these questions and throw in some action at the same time, with disastrous results. I would recommend this to someone who, like me, loves bad anime, and has some time they don't mind going to waste.
