This movie playfully answers the question "what happens when the non-beautiful people become vampires?"
Think of it as an updated Buffy the Vampire Slayer, but with multicultural stars. Most notably, a Fil-Am star, which is a very welcome and long-overdue change.
In this world, vampires are only supposed to convert new vampires who are beautiful, fit, svelte, cool, sophisticated. Enter Reginald -- the fat, awkward, unfit, remarkably un-athletic, uber-nerdy incel fast-food worker with no prospects. By a stroke of fortune and misfortune, Reginald gets turned. And the rest of the vamp community don't dig it.
Sure, this has Hallmarkish tones, and the dialogue and situations seem aimed to teens and 20somethings, but the series starts well, is funny, with some vampy coolness. Reginald is funny, albeit a shade too whiny, and incessantly whiny. Just when you think you can't stand it, it's revealed that there's more to Reginald than his girth.
