On paper, mixing Batman and H.P. Lovecraft seems like a total no-brainer. And if you set it in the 1920s, and feature the Caped Crusader battling ancient cults and supernatural foes with era-appropriate Bat-gadgets, then so much the better. Batman: The Doom That Came to Gotham — which is based on a comic miniseries from the early ’00s — has all of that. Unfortunately, however, it also tries to cram way too much into its 90 minutes, from the never-ending parade of Batman friends and foes (some of whom appear as alternate versions of themselves) to the convoluted retconning of Gotham City’s history to the overwrought dialog filled with old time-y phrases and oodles of Lovecraft references. And that’s to say nothing of the increasingly bizarre final act, which keeps throwing things at you (e.g., body horror, occult magick, more body horror) until it all just kind of falls apart. Note: If you want to watch a supernatural take on Batman, then you may be better served by 2017’s Justice League Dark.
