???????? I thought it was pretty mediocre.
It's the great violin playing that seals the deal for me.
Hm, I bought a box set of Chrono Crusade, but I have not seen it yet... that was a bold statement. There are few openings I'd compare to BGC, maybe GunBuster or some other late 80s mecha OAV.
I was strictly speaking of opening songs, not openings in general.
Then I came here and saw rad anime being compared to Evangina

The only thing that is overtly feminine about Eva is the pathetic main protagonist. There is some heavy shit in that show that alienates it from many female animu fanz who are more attracted to googly-eyed chibi girls, episodes that copy the same formula ad nauseum with no variation whatsoever, Pocky product placement, and androgynous looking men with deep voices in their anime instead of raw action and intricate story development.
Heavy stuff:
-Killing a child with your bare hands out of jealousy, then yourself.
-An entire army killing NERV personnel, unprejudiced against age, innocence, or gender.
-Achieving the successful self annihilation of an entire species for insane "higher" purposes.
-A narcissistic father who strives to meet his own goals, while treating his only son --who is a great deal responsible for helping him to meet these goals-- like shit.
-Psychological
turmoil inherited from the heat of battle on 14 year old kids.
-Etc.
Wussy stuff:
Shinji
EDIT:
Drauch, that opening is awesome!
