How can anyone watch this movie and actually think it makes sense?

Rating: 3/10 (21 February 2019)

I went into this movie pretty excited. I've been on a massive horror binge recently so after hearing so many good things about 'It Follows', I was pumped to see this. Lights off. Midnight. Big TV. Alone. Awesome.
What followed was a cluster of utter nonsense, sparse appearances by the least scary monster I've ever seen on screen and plain boring dialogue.
First I will say, the soundtrack was decent. Cool 80's carpenter style synth soundtrack, can't go wrong. Apart from it did go wrong, because despite the music itself being really nice, it did not fit the tone of the film at all. I feel a more standard modern orchestral ST would have fit the bill better.
Acting was alright. I feel bad for the cast as they didn't exactly have a great script to work with. The characters were boring, vapid middle class kids (?) with absolutely nothing to say to eachother. The friend (not the sister) with the dark hair and glasses - why on earth was she even in this film? What actually was her purpose apart from to make a few ironic remarks and act completely nonchalant about her friend being stalked by whatever the thing was meant to be?
Which brings me on to exactly that. The monster. What an ill thought out premise and antagonist. The first scene shows the audience a girl being killed brutally on the beach, her leg almost snapped off and mangled. Awesome, this is going to be horrifying. Nope, we have a monster that WALKS in a straight line until it gets to you and then kills you. Wow alright, so our protagonist surely just gets in a car/bus/taxi/plane/unicycle/skateboard and heads off until it catches up and repeats. Safe. Nope, she decides on multiple occasions to corner herself in an assortment of rooms and buildings so the only defence she has against this monster - fleeing - is rendered impossible. Smart move.
So she can't run because she's too preoccupied with cornering herself. So she has another option. Just as it was passed to her, she can bang someone else and then the monster will follow them instead. BUT if the next person is killed then it will just go backwards through the chain of sex partners killing them all. So cool we have some rules on how this thing operates. This is what confuses me. So the guy who slept with her to pass on this curse knows this, and tells her this, because he had it passed on by some other girl. A one night stand he says, where he was so drunk that he cannot even remember her name. So how on earth does he know all this??? He was drunk to the point he can't remember her name but somehow she told him about this curse and he can remember that? What? I'm assuming he wasn't told by this fleeting partner, as surely he would have tracked her down, so has he just figured this out somehow? Absolutely stupid nonsensical was of explaining the rules to the audience.
The film goes on like this until the end. Every 5 minutes watching this film I found myself saying 'What?' out loud.
Why did she sleep with the random sleezy guy in the HOSPITAL??? Was he that desperate to bang her? Like surely this guy would stay well away even if there was an inkling that what she was saying was true.
Why the hell did the other dude (the 'nice' guy) sleep with her later on??? To show how much he cared about her??? Absolutely obscene.
That ending... wow... why on earth did they think it was a good idea to put her in a swimming pool and surround the pool in assorted electrical devices and plug it in? So they could lure the monster in and electrocute it? What could possibly go wrong? The dude at the beginning who gave her the curse even said 'its slow but not stupid'. The monster wasn't stupid, but the characters certainly were.
Where were the parents in this movie? 5 kids running around up and down the country, windows getting smashed, car crashes, one of them even gets shot. What the hell?
My favourite part of this movie was when the leads friend asked her 'what does it look like?' and she says 'I don't wanna tell you'. Here I was thinking we were going to see some absolutely rotten vile monster. It was a well kempt dude in shorts. Wow. Scary stuff.
Honestly I'm done writing about this, this is the first review I've written but I was just so appalled by its own stupidity that I felt impulsed to write my thoughts out.
Don't watch this film. It stinks.
