The visuals and artistry were very good and surreal but whatever. The story/plot if there really was a cohesive one sucked. I mean, not like I think I'm all brainy and stuff but almost every review written had no clue where the movie was going and there were some professional reviewers too. I can appreciate leaving something to the imagination but come on! What happened to the humans? Where and why is the city underground (is it?).Super biomechanical machine that can alter a robot just laying around but not a single scrap of info to give the veiwer a hint at WTF is going on? It just seemed that this dude did not care enough to plug in the amazing number of plot holes. And because of that, it sinks like a ship. Now, I think that everyone should rent and watch this once. Why? Because misery loves company and I want you to suffer too. LOL! Oh BTW, I did not watch this CG expecting a hentia.
