I had watched the series on Adult Swim in English. The way the last episode ended was both interesting and slightly frustrating. I liked the series a lot though. One main thing about it that I found interesting was that it seemed like it went into an idea of the complexities that human thinking..used to have.

Also that what were called angels seemed to have a version of judgment of what was best for mankind that most would find cruel.
I believe you can find the Evangelion movies online, though I'm currently a bit confused on which order they are supposed to go in.
