OH. MY GOD. IT IS SO MUCH BETTER THAN THE ORIGINAL SERIES. Less hopeless tone! Better animation! Even better music! More likable characters! A Gendo who's realistically aloof and neglectful and not an over-the-top unfeeling monster! Plots that make sense! Toned-down religious imagery and a move away from Freudianism in depicting the characters' thought processes! I believe at this point that Rebuild is what Evangelion should have been all along. But then, if the original hadn't existed, this couldn't really be what it is: explicitly the salvation of Shinji, Asuka, and Rei.
I like the original Neon Genesis Evangelion series okay--I have the DVD set--but it's never been a real favourite of mine. Now? I think Rebuild might be up there among animated movies, though not at the very top. HOWEVER! Two movies to go. WE WILL SEE WHAT HAPPENS.
I also watched Summer Wars, which I loved A LOT, but then, I'm biased, since I have a very large extended family that's a lot like the one in that movie.
