It's a great series, especially the psychological aspect of it. I think I'm one of the few who liked the End of Evangelion ending and how crazy things got. xD
The Rebuild of Evangelion movies take place in an alternate timeline; things are changed quite drastically from the third movies onwards compared to the events of the anime. It's supposed to have a completely new ending as well. The final movie in the Rebuild series is scheduled for a 2015 release in Japan, but it might take up to a year for it to be released overseas.
