Again (Intro 1) was awesome. Could be considered "classic" if it wasn't so new. Due time, due time. Hologram (Intro 2) was pretty cool. I rather miss those more lighthearted intros. Golden Time Lover (Intro 3)? UGH! I hated that one so much! That had to be the worst animé intro I'd ever seen up until watching Hellsing. It was so boring, and as soon as it started to pick up, it just got cut off with some extremely lazy editing. Period. Oh... my... word. They totally made up for that last one. The fourth intro was the very first animé intro I ever saw to make me suddenly rewind it a moment after it started in a frantic state of "Waitwaitwaitholdon! Startovercauseiwasnotreadyyet!" Not often does an animé intro leave me gaping in awe like that. The only other two I can think of that did that were the first intros to both Soul Eater and Attack on Titan. Oh, that last one. Rain (Intro 5)? I don't even remember what that one was like. I think it was kind of soft, but that's all I can recall. I was rather disappointed to see that last one go.
