Writer-director James Gunn’s “Superman” was always going to be a strange chemistry of filmmaker and material. Gunn, the mind behind “Guardians of the Galaxy” and “The Suicide Squad,” has reliably drifted toward a B-movie superhero realm populated (usually over-populated) with the lesser-known freaks, oddities and grotesquerie of back-issue comics.

James Gunn's "Superman" film is Warner Bros.' attempt to reinvigorate a DC Comics film universe that has been a mixed bag over the past decade. The intrigue: The movie is a crowd pleaser that gives stans of the franchise plenty of moments to geek out over.
