I have seeing various "What's your favorite OP (ED)?" threads on various forums, but it's usually based on the songs used for each.
This time, however, I want to know what peoples' favorite OP and ED(s) are in terms of the ANIMATIONS used in them, completely regardless of the songs. Well, actually, you can take the song into account IF it helps with the animation used for them, but do not base your answers solely on the song. (Like how DISCOTHEQUE for Rosario + Vampire Capu2 helps greatly illustrate the disco dancing done.)
And be sure to say if you like the OP and/or ED of named anime(s). If they happen to have different animations as the
series goes on, which one (1st OP, 2nd OP, 1st ED, etc). If you want to, you can also give reasons why.
Some for me would be...
Rosario + Vampire Capu2 (OP)
Clannad (~After Story~) (OP)
(Shin) Koihime Musou (Otome Tairan) (all OPs and EDs)
Princess Lover! (OP)
Higurashi no Naku Koro ni (Kai) (Rei) (OPs)
Umineko no Naku Koro ni (all OPs)
Angelic Layer (OP and 2nd ED)
Inuyasha: The Final Act (all EDs)
K-ON! (1st and 2nd ED)
etc
