Worst Plot Ever. The actors must be ashamed

Rating: 1/10 (30 June 2017)

So I thought "Hey, Clooney and Tarantino, how bad can it be?" It was the worst movie ever! Full of clichés, stereotypes, plot holes and even stripper-vampires!
Until 50:00, it was a relatively good movie,with villains, psycho - sex offender brother, kidnappings, of course there were many unanswered questions, but it was fairly entertaining.
All if a sudden, the dancers in the strip club turned into vampires and started attacking everyone. The ways you could kill them were the classic stabbing in the heart, crosses, sunlight etc. Not only was it cliché, but the characters reactions and behavior towards each other were everything else but normal. This whole family must have had Stockholm Syndrome. Nothing else can explain why they didn't kill their kidnappers, but instead helped them. They even sacrificed themselves! In the end, Seth and Kate defeat the evil beasts/strippers/vampires, Kate's family is dead but she doesn't even blink, also Tarantino(G.Clooneys brother) is dead, but he, the vengeful criminal, just lets it go by demanding a bigger percentage of the earnings from the bad guys. And here I sit, wondering:
HOW THE F**K DOES IT HAVE A SCORE OF 7.3/10?
