I just finished Neon genesis evangelion and it's f*cking amazing, it's the second "old" anime (with Chobits).
I think I like the sci-fi anime because three of the actual five anime I saw (Plastic memories, Chobits and Neon genesis evangelion)
I've really appreciated 'em ^_^.
If you have any anime you've seen and enjoyed it please tell me them ^_^(especially if they're sci-fi and is related to AI).
I may try to draw Rei :))
