Shaun of the Dead plus Office Space plus BtVS = Bloodsucking Bastards. You could do much, much worse - and I have.
Evan Sanders (Fran Kranz, Dollhouse, Cabin in the Woods) is having a rough time of it. He is the acting sales manager at a telesales company, with an apathetic sales team comprised of bros and weirdos. His girlfriend just dumped him and she works in the same office so he sees her all the time. Just when he thinks he's going to be promoted to sales manager, his boss hires someone from outside: Max (Pedro Pascal, the Viper from Game of Thrones), Evan's douchey nemesis from college. And just to rub salt in the wounds: Max is a vampire and he's on a recruitment tear.
Bloodsucking Bastards is a lightweight horror comedy. It's pretty funny and has buckets of blood but is never actually scary. It's clearly lower budget than Shaun of the Dead or Slither, and yet has its own charms. The characters are actually well-developed and the way they act makes sense for who they are and the universe they inhabit. I'm not sure it's ever found much of an audience but I'm glad I found it: its cheerfully bloody tone has encouraged me to press on with scary (or, "scary") movies for the second half of October.
