No, it's not a masterpiece that would deserve 10/10 as some have rated it here. But it's not a total crap either so it doesn't deserve 1/10 ratings either.
The story as a whole is actually good, something different. There are few jumps scares, some better than others, there's some creepiness at times. It's supposed to be a horror movie but at times it felt more as fantasy - I think that might be one of the reasons why this movie is rather weak, the director couldn't make up his mind what genre to choose.
The main actors, unfortunately, are terrible. The few ones that are actually ok play only secondary roles. The parents are annoying, you actually hope that at least one of them would die - they're so unlikable (I won't say if anyone dies or not because I don't want to give spoilers). Some the dialogues would make your eyes roll as well. I don't know what went wrong, the movie had so much potential to be so much better. I thought it might have been the budget but for 9mil (to compare: Babadook had only 2mil) I would expect something better.
In short: it's an "ok" movie. Definitely something different. The 5.9 score it has at the moment is fair.
