Be aware that the manga, anime and the movie are all different. I recommend you start it with this order: ova-anime-movie-manga. At least, this was the one that worked for me, just change it if you want to.
Why not the novel? Well, if you'll be able to find it somewhere, then read it after the anime.
STORY
As you read before, the plot is Terra vs Mulians, the ancient people with blue blood that wants to regain the world from humans, the red blooded people that has their hearts full of despair.
The story evolves Ayato's being the only pilot for Rahxephon, a god who controls fate but it's main goal is to grant pilot's happiness/desire.
ART
Oh, the times where anime wasn't full of CG effects and Bones focused more on quality than popularity.
Besides Rahxephon is from 2002, that are some good animation going on, better than some of these new popular series out there.
SOUND
Here comes one of the most important parts of Rahxephon, the world needs a retune.
You will notice that not only the Xephon but also all dolem's have a voice, a tune. Even Quon's urge to create the perfect melody and constantly singing.
But the main thing here is the soundtrack, search for it and if I'ts possible, read the op and ed lyrics.
Plus, there's a song called "The Garden of Everything" that has a deep connection with Ayato and Reika.
CHARACTERS
Through the series, the main characters development is pretty clear, there is nothing inexplicable.
Quon's might be hard to understand if you don't watch the OVA or don't pay attention to her riddles.
Ayato is definetly one of the most easy to get characters ever. His desire to know himself is completely undertandable, just imagine being at his place.
Reika is actually the most puzzling. You'll get angry at her during all the series but when you finally read the manga boom, all the answers.
ENJOYMENT
If you are into drama, romance and psychological anime with some mecha into it, then watch.
I won't be saying too much here because you probably will say that I'm biased even though I'm being realistic.
Please, be aware that if you come to me talking shit like "rahxephon is a shitty eva rip-off" I'll just answer you one thing, watch the fuck out of BOTH SERIES.
If you read and watch the whole eva and xephon series, you'll understand that IT'S NOT A FUCKING RIP-OFF.
Bye.
