The following contains MAJOR spoilers for The Flash.
The Flash is a movie that seems designed from the ground up to be a huge nostalgia trip for any and all big fans of DC’s pantheon of comic book heroes or at least anybody who has seen all the movies based on those characters. Not only is Michael Keaton’s Batman a big part of the movie, but the film’s big multiverse finale gives us numerous cameos (both authentic and digital) from some of the greatest heroes of comic book movies’ past. And also…Nicolas Cage.
