This is a fan service movie built by people who understand what Inazuma fans actually want: characters you've waited years to see interact finally on screen together. The Hissatsu techniques hit with full animation budget behind them, and the soundtrack swells exactly when it should. There is no story here, just a match, which means nothing gets in the way of watching your team win.
Inazuma Eleven: Choujigen Dream Match is a single-episode sports movie from 2014 with a supernatural streak. Its centerpiece is one match: a lineup chosen by fan vote, known as the Inazuma Best Eleven, takes on a specially assembled side called the Battle Eleven. The whole film is built around that showdown between the two teams.
