Great movie! If you want to be entertained and have a few good laughs, see this movie. The music is also very good,

The film's masterful storytelling did its job. The message was clear. No need to overdo.

It's a feast for the eyes. But what really makes this dramedy work is the acting.

The film never slows down or bores, plunging from one harrowing sequence to the next.

I hate cliffhangers and there was one at the very end. We discover Tira is the bad one and that's when it ends. What the...?

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.

American sculptor Jess (Katee Sackhoff) tries to reconnect with her estranged daughter Chloe (Lucy Boynton) in Britain but she rejects her after a 9 years absence. Chloe and her friend Danny visit a nearby abandoned house. Former occupant Mary committed suicide after supposedly killing Chloe's friend Michael. The rule is to knock twice. Once to wake up from her bed and twice to raise her from the dead. They both knock and ditch. Danny gets haunted by a demonic spirit and is killed. Chloe is next.This is derivative of so many other horrors and it's inferior in many ways. There is nothing new and not much of it is done well. The characters are sculpted poorly. It's hard to feel for the relationship when there is so little invested. The characters have no depth. The movie takes us to a haunted house but we don't get to go in right away. Honestly, there's an easy road to a solid indie horror. It's a simple haunted house horror if the two young people go inside. Jess can then come to Chloe's rescue. It shouldn't be that hard but the movie is intend on making it that hard. It becomes a confusing road to travel which wraps up with an explanation. I guess the plot works but it's not compelling as it unfolds. As an aside, there is a lack of specificity to the setting which is needed. That's where more background on American Jess would help with the British setting. This is a lot of nothing and I wanted good things for Starbuck.

What a load of rubbish.The horror genre is riddled with bad movies, and is an arena most fresh film directors like to enter, as it is fairly straightforward and doesn't require the same skills a serious drama does. The problem is: to make a really good horror, you do need a lot of skills. Whoever made this had no idea what they were doing. The script is lazy and predictable, with one overused cliché after another. It's so tedious and frustrating. And then there's this ridiculous premise with an interracial couple... Guess what race the girl is? No surprise there.This film is absolute bottom.
