I just rewatched The iDOLM@STER Movie again and again, and it's such a beautiful movie.
I really like the fact that 765 Pro wore modest outfits, while Million Live wore skimpy ones.

EDIT: I also rewatched Civil War this year as well, and it's such a really great movie.
I didn't expect Iron Man and his crew were to participate another non-Iron Man film.
