“Hellraiser” has risen from the depths (or beamed in from another dimension). And the movie, now streaming on Hulu, adds considerably to the already established “Hellraiser” lore (originated by Clive Barker’s novella, which Barker himself adapted into the first movie) while also making it easily, um, digestible for those who are new to the franchise. Listen, you’re going to have to learn about BDSM space weirdos at some point; why not now?This new “Hellraiser” concerns a young woman named Riley (Odessa A’zion), a recovering addict who is desperate to get clean.
