Hawk and Rev: Vampire Slayers (2017) online

Hawk Hawkins doesn't just dream about killing vampires... he eats, sleeps and breathes it. After getting kicked out the Army for staking a fellow soldier, Hawk finds himself working as a night security guard at a deserted office park. Just when it looks like all his options in life have expired and he might die of boredom, low and behold, vampires appear on his watch and of course... Nobody believes him! His back against the wall and out of options, Hawk takes matters into his own hands, enlisting the help of his dimwitted janitor friend Rev to help him save the world from evil blood-sucking Vampires, or at least his town anyway
