Now that the official theme song for Evangelion 2.0 has been released there seems to be need for further discussion.
This is what I think about it: I think it's pretty amazing that there wasn't any copy available on the internet before the release two days ago. No title officially announced and no information at all. But because of this particular reason people seem to be even more disappointed to get "just" a remix.
I don't like people to appraise this song as an ordinary single, because it's a THEME SONG! It's a remix, it's for Evangelion and it's very well done. Evangelion always had one opening theme in many variations and this fact represents one important topic in the anime series: showing differences (feelings, impressions, ...) in human mind and changes as well!
In this case isn't a remix most suitable? Because a remix isn't just a warm-up of older stuff, but an (re)inter•pre•tation! Btw: The Rebuild of Evangelion movies are meant to show a certain climax. Doesn't this remix contents a different mood than the originl song?
Finally there is nothing more to say as that this mixed theme song is well done and suits good to the second Rebuild of Evangelion movie. Especially because in my opinion a guitar goes with Asuka, who has a main role in this movie. Maybe I got this idea because of ASUKA STRIKES! :)
