Though loosely based on Marvel comics characters, Hulu’s Helstrom eschews any connection to the MCU, wanting to stand alone as a horror series more in line with the CW’s early aughts output. If you’re sad that Supernatural is winding down, Helstrom seeks to fill that void with a new pair of demon-slaying siblings. Except, instead of the former’s affable charm, the latter offers a team of brooding, unhappy siblings, cliched possession tropes, and worldbuilding that’s not near as expansive as it thinks. At least in the first five episodes screened for critics.
