It definitely has plot holes.
For instance in sn1 when Vanessa's daughter was being threatened by the crazy doc with a KNIFE!! I mean a vampire + knife??
Scarlett literally jumped out of nowhere with too much 'pizzaaz' 😀
Then.... Is it a vampire world or a zombie world?? Make up ur "mind"
Plus this whole series is a rip off of
Resident evil, the walking dead.....
