I wanna watch the top one.
Eureka Seven re-ignited my desire to watch animé
The last one, being Rebuild. I f**king love it. Especially on my 50"HD extremely vivid TV, the scenes where they catch that Angel coming down like a rainbow and the last scene of the 2.22 are freaking gorgeous! It's like watching a real life Aurora. LOVE IT!
It;s hard to choose, because there is quite a few mecha out there. I think the majority of people might say Evangelion. If I say it, it's only the Rebuild ones. 2.22 is perfect to me.
