I have not played the games, only having observed a little bit of play. I definitely don't know the story.
I enjoyed the first movie. Some parts of it were really great and there are some slog moments that I will even skip past now. Overall though, the first is a guilty pleasure. I can't recall a lot about the second movie except that I hated it. Kit Harrington was super hard to watch, some weirdness with CGI stuff in the end, and something about the big sword boi really upset me. I don't think I ever watched the second flick again.
I want this new one to be either good for the fans or if it misses then at least fun like the first one was. I really do need to give the remake a try, but I am such a chicken for interactive horror.
