The im@s movie is what one would call "life changing medias". It is so well written that it could've perfectly been its own anime arc.

Starting the movie with a trailer for an in-universe movie is a genius move that only works for idol anime. Fate of the World is pretty much a timeless classic when it comes to 765 pro and the visuals make the song even better.

A stage with back dancers is not something usually seen in idol anime, since most if not all focus in just the main group, so its something more outside the formula that worked out really well in both concept and execution.

M@STERPIECE is my favorite 765 pro song and listening to the leitmotiv and different arrangements during the movie which led up to the final version is truly an experience.
