Refracted plot holes

Rating: 3/10 (24 March 2018)

I expected a fantastic movie that makes you consider alternatives to what one considers normal or even obvious, like Arrival (2016). One with a mystery and a challenge for characters to overcome.
I got a well-marketed, but ultimately crappy horror B-movie running on stupid. It's like Alien: Covenant (2017), but with worse effects and less action to distract from zero-dimensional characters, pretentious plot and unpalatable babble. What's distracting are random "sex" scenes that do nothnot but ruin any pacing this movie had left.
What is said and what happens is annoyingly inconsistent, infuriating even as there is an attempt to pass it as a mystery. When you accept the characters are just rambling nonsensically just to spook you, you realise there wasn't any challenge at all, either, which obliterates any tension. It basically amounts to "oh no, there's a weird looking bug in the toilet bowl". The ending simply demonstrates it, disappointing any hopes of an interesting subversion. I just flushed.
