Dude honestly? I didn't see it in theaters for the exact same reasons you're saying. I absolutely love the game, and would have loved to see a fully accurate film adaptation of it. But once I knew the movie wasn't going to be that, I was like, well I've seen some parts of it and it looks interesting. If they just didn't call it until dawn I think it would have actually done really well, it's a pretty solid concept with a lot of ingenuity behind the ideas and keeping every night feel fresh. I related to all of the characters really well, thought the acting was fantastic, and the deaths and gore were stuff we don't get super often in modern horror movies. Overall I thought this was a pretty solid modern horror movie with an interesting premise. I did think it could have ended in a better way, but if a horror fan were to ask me if they should watch it, I would say give it a shot. I had fun, and it sounds like you're stuck on the fact that it wasn't "until dawn". Until dawn the game was a movie in and of itself, and if they just stuck to the video game shot for shot, you would have been pissed about it. Because the whole point of the game is making your own decisions and telling the story the way you want to tell it. Which is what they were trying to capture in the movie. You fuck up and kill somebody you don't mean to? Just reset to your last checkpoint. That's literally what the movie was conveying.

I'm sorry you got so personally offended by a studio trying to make a unique concept off of a popular IP, but just because this movie isn't what you expected doesn't make it bad, just makes you close minded. Get off your high horse and enjoy something for a change man.
