Someone noted how this new opening makes it seem like a "final" opening, which I can understand. They even flash back to stuff from the very first season/story arc, which is interesting since this section of the story does the same in some ways. Even though it makes sense, I'm still surprised how much Gin is shown this time around. I really wish the TV series itself would have better animation like the opening and ending, though.
Also too busy loling, so I'm going to leave this here: Ichigo does not want.
