One word: Awesome
I once read a quote about Neon Genesis,
"It's strange that 'Evangelion' has become such a hit - all the characters are so sick!"
... I gotta agree with that... the characters are always struggling with relationships, their own personalities, and their past.
It's a great anime, and if you haven't seen it, you need to.
