Problems

How is he the head vampire? Does Dracula exist in their universe? Is max supposed to basically be their version of Dracula (got his power from making a deal with satan). If one of the bad vampires survived after max died, would they also return to normal, even though they’ve made their first kill? What happened when Michael “falls” into his bed after falling from the bridge- the mom says he walked in during the night? Is it like dying in a video game and you start over at the beginning, which is just where he woke up the previous morning? And most importantly, HOW THE FUCK did Michael and grandpa time the pointed posts shooting through Max’s body? I love this movie but all these need to be addressed in my opinion.
