While Ghostbusters: Afterlife set up one potential series twist, Ghostbusters: Frozen Empire now has a chance to follow through on this premise. The Ghostbusters franchise has a pretty simple conceit that is effectively encapsulated in its title. The heroes use their ramshackle, homemade technology to capture and contain ghosts, ghouls, and other supernatural phenomena. Despite their brand, the Ghostbusters don’t just deal with ghosts. Instead, they have been known to handle demons, ancient gods, and all manner of other paranormal problems. Consistently, the Ghostbusters are portrayed as forces of good, containing the chaos caused by the supernatural world’s unruly denizens.
