Ahh, Neon Genesis, this one is complicated. First time I wacthed episode one, I was confused, second time even more so, by my third viewing of episode one, I realized that I hadn't seen any newer episodes. I treked on, coming to understand what the hell was going on. By the last two episodes, I was exhausted. They were not the most satisfying, so I went on to End of Evangelion (the movie).
The show itself has awesome action, an unforgettable intro, and a story so complex and so confusing, you will probably never understand it.
But it is so worth it. Plus every weeaboo must watch this, it's like a law.
