Oh s-s-s-hit, you messed up! Just like me.
Yes I have watched Rahxephon and it is excellent! Where we both messed up is that we didn't have a mind-set to watch an anime of whom the story was partially a mindf*ck. Or more like there was "some weird shit goin' on" as anidb tells us, we didn't pay the much needed attention. Go read the review of Rahxephon on Animenewsnetwork, you'll start liking the anime more.
At first my impressions were also, "Rahxephon, hmmm... it is a so-so anime" but then when I thought deeply about the story I started to like it more. The "human instrumentality" part in the end gave me brain-cancer because of which I called Rahxephon a so-so anime, but I was dead-wrong. It's amazing. Evangelion is pretty much like Rahxephon with the philosophy of humans and their existence, the human instrumentality project.
Yes a real movie with real-life humans
