I can only watch it in Japanese. Not because I prefer subs to dubs, but because the voice actors in the English version are atrocious (especially Shinji). So I watched Evangelion back in summer and I thought it was pretty decent, but it fell apart near the end. I know that the reason had something to do with the director having major depression, irresponsible budgetary spending and some drama to do with fans being way too involved, but that's only what I've heard.
I thought I was really going to hate Shinji a lot. I mean, don't get me wrong - I really don't like him as a person, but I think as a character he is very interesting due to the fact that he is the absolute worst kind of protagonist, which makes him more human. That doesn't change how frustrating it is when entire episodes are devoted to his pig-headedness.
I think I'll need to watch it again (especially near the end).
