(Spoilered anyways.)
The first half up until Asuka's struggle against the Mass-Produced EVAs.
Upon hearing Asuka's voice and fueled by Misato and Kaworu's deaths, Shinji gets up and goes into EVA Unit 01.
Before the "replica" Lance of Longinus could even be stuck into EVA Unit 02's head, Shinji grabs it and moves it away from Asuka. He gains control over it and EVA 01 goes into Berserk mode. With his mother's spirit by his side, Shinji brutally murders all of the Mass-Produced EVAs.
After that, he goes down into the area where Lilith is. Before Gendo can even begin his attempt to fuse with Rei, the Berserk EVA 01 kills Gendo. Since Rei can't be talked out of it, Shinji says farewell and kills Rei. Memories of her flow through his mind during this. Ritsuko and everyone else survives (except for Misato.) Third Impact averted.
Final scenes include Misato's funeral and Shinji visiting Yui's grave (and possibly Gendo's grave?)
+No psychobabble (The other person who viewed it with me thought it was too much.)
+Shinji mans up
+The world is saved
+Asuka lives
-Misato is forever dead
Feel free to disassemble and analyze it, I wrote this up a bit fast without sifting through the Evageeks wiki and stuff.
