Fabio, you're one odd guy: You mentioned how you didn't like Trigun, which I assumed meant you wouldn't be too hot on the sort of shows that tried to capture its episodic and fun qualities, yet you seem to like GxS a lot. What's more, you've actually added a pole dancing, mecha riding...person to your favourite character list, alongside Van.
Bad taste is bad. I suggest watching Death Note until you see its greatness in order to attempt to cure yourself. Or, if you want to watch 135 episodes, I suggest watching Naruto until your taste improves.

Anyway, enough random rubbish.
Since I recently managed to complete my Rahxephon collection, I decided to give Vol. 1 a look. I thought the first five episodes were great, with some loveable characters (depending on if she dies, one might find herself on my favourite character list) taking up a lot of the screen time. Looking forward to watching some more tomorrow.
In the distant past, I vaguely recall dropping it around the halfway point... I think it was down to some level of confusion over the song effects. Like with X (TV), I'm going to make sure I complete it this time around now that I own the DVDs.
