I loved the ending of Evangelion. I'm one of the people that believe the ending of the TV series and End of Evangelion coexist. The last two episodes of the series are what happened in the mind of Shinji during the End of Evangelion.
If you haven't seen End of Evangelion and don't want to be spoiled I wouldn't read further.
Here's Hideki Anno's explanation of the last line of the movie, the much disputed, "Kimochi Warui." Basically, the voice actress who played Asuka was having trouble figuring out exactly what and how to say what Anno wanted her to say. So, he described it to her something like this, "You were in a room, alone and unconscious, with someone. Even though they could have had their way with you, they instead masturbated to your bare breasts. How do you feel?" Of course, she said "kimochi warui" which can be translated to 'disgusting' or 'i feel sick.'
Though Anno explained that, he didn't touch what the entire scene meant. He has been quoted as saying something like, "Anyone who has a perfect health social/mental life will get nothing from this." So, it is meant to help people who are having trouble in their lives, and who the hell isn't. Basically, the ending is meant to mean what you want or need it to be.
If you don't understand End of Eva or even the series watch it over again (I've watched it like 5/6 times), read into the plot and empathize with the characters. You can read some online explanations, but the biggest thing to take away from Evangelion is to come up with your own conclusion on what it's about.
My personal theory on Shinji is that his type evolved throughout the series from an INFP to and INFJ.
Anyways, if anyone else out there is an Eva fan I'd love to debate and converse different theories.
PS. Tamagochi- I loved Bakemonogatari, I can't wait for the next web episode!
