I personally don't believe EoE is necessary to watch, you can get exactly what you need to get out of the series itself. It requires alot of introspection and reflection. You have to put yourself in Shinji or Asuka shoes and say, "What would I do if I were them?" The show helps you realize your own fears and insecurities and feelings of self-worth and shows you how you can handle them. It shows you both roads you can travel and where they both lead to. I don't think EoE should have even been made, it seemed to me like alot of people missed the point of the series, so they made a movie to fulfill the angel story. I was completely happy with the series ending, and didn't see EoE for a few months afterwards. You just have to dig deep within yourself and teach yourself something, the series doesn't just hand it to you (like the movie). The deeper you dig, the more you'll learn and understand about yourself. If you don't do anything except wait for an explanation about the characters on the screen, you won't get anyhting. I feel that the series isn't abot those characters, it was about me. And after reflection of the events that occured, I came to a great revelation. I hope you do the same thing too.
Here's some links from a while back when I was confused and someone pointed me in the right direction.
