eh. looks a bit generic.
Also, going to have to do some real work to sell me on how this super trap house was built. a problem with "trap house" movies. especially after games. they get bigger and bigger, and more complex. original texas chainsaw was just a house with a basement.. silence of the lambs.. house with basement with dug well.
and even with that, so many trap house movies, going to need something interesting to sell it. The obvious I would think here is, this guy is part of their church. so, hes not some rando, that was just waiting for people to show up at his trap house. The church is in on it, and actively sent the young missionaries to test their faith. I think that would be a viable twist. explain the how and why. bonus points if the indoctrination works, and the girls do come out of it with a revelation and are even more zealous in the good work after.
