kosmasp You know I've seen worse horror movies, but I also have seen way better horror movies too. The cliches are there and even if you may not know everything from the start (a twist or a turn or whatever), overall it is predictable. So shocking would not be an attribute I would attach to the movie (except from some jump scares).Of course this may be the only reason you tuned in, in the first place. So if that's the case enjoy the ride, do not think about logical errors or irrational behaviour and it will be fine.

bayupahleza Never heard this flick before, and found later that this is not Hollywood's. The demon is scarier than James wan's old hag, and had few jumpscare moment. The acting was nicely done for both (mother and daughter). But don't get too excited, don't knock twice has big issue, atleast for me who always has interest in horror flicks. The plot, yes the plot wasn't something new. It was same pattern which overused and been around for a while. It's hard for me to focusing my self to the movie, because the plot bores me a lot.

rbcoral77 A few creepy scenes, good twist. A bit blueprinted but a pretty good movie.

Platypuschow I wanted to like this I really did. I watched the trailer and thought to myself that this had potential, this is the one that will turn the tide.Alas I was wrong.Starring Battlestar Galactica's own Katee Sackhoff this highly clichéd standard Hollywood formula horror takes an interesting concept and neuters it.It granted does get under your skin a bit and isn't scare free but as for originality, as for competence, as for entertainment not so much.It tells the tale of an urban legend where if you knock twice on the door of an abandoned house then the witch who once resided within will come after you.What comes next is a blend of several movies including Lights Out (2016) but it just fails to bring anything new to the table.Again I wanted to like this but simply couldn't, I've seen it all before and done considerably better.The Good: Neat concept Creepy in places The Bad: Failed vision Whole thing feels stale Things I Learnt From This Movie: Hollywood is really pushing this crappy protagonist thing on us, I'm expecting a heroic rapist any movie now.If your daughter plunges into a hole in front of you don't follow........that would be silly
