Lots of effort, ultimately fails.

Rating: 4/10 (26 September 2019)

*Minor* spoilers in the review.
It's difficult to organize my thoughts on this movie, and speak to the extreme reviews (seems like people are either ranking it 'amazing' or 'trash', and its neither).
There is well done suspense and 'scary' moments to the movie; a lot of care was put into this, which I appreciated.
The movie is very 'ambient', and well done in that regard (some reviews are calling this aspect 'slow' or 'bored me to tears', but its purposeful and well done in this regard, in my opinion).
Why am I giving it a 4/10; the movie manages to make virtually every single possible 'horror movie failure' possible. The main character is told exactly how the evil thing works, and even after accepting that its real continues to ignore what she and the audience know about it. She knowingly follows it sometimes, why? There is literally no point other than allowing the audience to 'see' it in action, but that could be done on camera without her present. She manages to harm it at one point, but then gives up on trying to kill it for no reason. It has to interact with the physical world, its not some magical thing that just *pops* up wherever it pleases, so she could try and get 'official' help (police, etc) but never attempts to. Soundtrack and a lot of the scenery and surroundings make it seem like its set in the 80s but there are modern cars and electronic devices. I found myself constantly wondering where we were and what year it was. You know the movie isn't 'doing it right' when you *constantly* are yelling 'WHY ARE YOU DOING THAT?!' or 'DON'T GO IN THERE' at the screen. And these aren't cases where the audience is privy to information the characters on screen are not; they have experienced *exactly* the same thing as the audience, no 'reveals' to just the audience.
I really wanted to like this, as it is different than a lot of horror movies, but ultimately it was a massive disappointment due to the numerous and obvious flaws and falls prey to virtually all horror movie tropes (not in a good way).
Oddly enough, I do recommend watching it, but if you're looking for a movie to fully engage you and give you a REAL scare, this is sadly not the one.
Edit: After reading ALLLLL of the reviews currently on IMDB about this film I felt like I had to add something in response to what I'm seeing in my own review.
Probably unsurprisingly, most reviews are 'polar' (either 1 star or 9or10 stars). The 1 star reviews are mostly complaining that its boring and that the 'thing' in the movie is never explained as to what it is, and that something slowly walking at you isn't scary. To these people I say that they aren't horror fans, they're not looking for an actual *scare*, they probably want a slasher or something along those lines. For something to be scary you don't need an explanation as to what it is, in fact, in general that makes it all that much more scary.
The other side, the 9 and 10 star reviews praising the film for how amazing it is. Do I get the 'hype' in that regard of it being 'refreshing' and not the same crap that every other horror movie is? Absolutely!!!! But these people must be blind as there are *sooooooo* many plot and logic issue with this film, which are specifically the reason I'm giving it a low rating. If somehow magically the film didn't have massive plot issues (which I haven't touched on even half of them in this review, trying to leave something for people that want to give it a chance) I would easily give this a 10/10.
I wish people would be honest with themselves and in these reviews, not just blasting immediately to a 1 or a 10. That's not a review. That's ignorantly trying to force people to like or dislike something because you personally love or hate it.
