Ready 2 Not
I think this is the type of slasher/thriller film that can easily be turned into annual franchise especially the movie was made for less than 10 million. They literally could make a dozen stories of f***** up families and make different variations of the newly wed couple and their relatives. But this isn't Lionsgate, Paramount, Universal or Sony, its Searchlight. So I don't think there would be a sequel. Unless the eXecutives of Disney want a slasher flick every year that won't be streamed in D+, okay but thats a longshot.
As I was saying, I wish the family members had more backstory. The film was quite short and I wish the other family members had their own death scene instead being slaughtered in the end. Like I was interested to see what games they actually played when they entered the family, and the people that were killed in the past. I wasn't really into the supernatural stuff as I usually avoid those kind of films but the premise of this was really intriguing.
