Really? Even now it's still one of my favourites. Apart from the fantastic visual direction, soundtrack, and Anno's characteristic style, I love the way it plays with the viewer's expectations and I admire its authentic treatment of depression (Anno himself suffered from clinical depression at the time, which is reflected in the direction of the story.)
I can imagine coming away from it slightly disappointed if you didn't finish with The End of Evangelion movie, but in my opinion, the final two TV episodes are underrated.
