However, the Zack Gaiden part of the movie is way more emotional for me, and it is the only one to take place after the series.
Zack is one of my faves and him wondering if he did the right thing in the beginning is touching
also, it shows a beat rider actually caring about dancing after episode 12
it's a grounded and touching story that seems more true to the beginning of gaim while still being serious than the actual series ever managed to, with some interesting insight and such into how Team Baron was formed.
Even the main conflict isn't straightforward, it's a fight between two different people interpreting the true desires and will of Kaito differently, sort of like the Boss
Most importantly, Zack being a badass. Even Oren gets a few scenes of coolness, too. EVEN MICCHY gets to be a kind of cool guy.
A+
