A welcome return to low budget, minimalist horror

Rating: 7/10 (6 June 2015)

Being followed is more frightening, and prolonged, than any other type of scare, as this weird, wholly original low budgeter proves. A young girl finds a shape-shifting supernatural being following her after a bizarre sexual encounter.
Is "it" a metaphor for sexual regret?
She then attempts to figure what "it" is, and how to rid herself of "it".
Clever film wisely avoids shaky cam, and needlessly cheap jumpscares, instead building feelings of dread and fear and unease. And disorientation: people have cell phones and tablets, but also 1970s television sets (and a lot of them shown throughout the entire film) Does this occur in present day, 2010s, or in the 1970s? And where is the story set? It almost looks like California in some scenes, maybe Detroit slums in others (pool scene takes place in an abandoned Detroit Rec. Centre, though)
Subtle, quiet horror also benefits from its intentionally disorienting photography, in which the background action is the focus of some scenes, not the foreground.
Story implies that she gives "it" to someone else, with the intention of him quickly giving it to a prostitute- but it wouldn't take "it" long to stalk and kill them and be right back after her again. The same can be said about implications of her banging one or more of the guys on the boat in the lake.
Abrupt, anticlimactic ending, yet it works on several levels.
I didn't understand the purpose of the flatulent, constantly chewing character, Yara, who seemed to be nothing more than a pity friend, someone the main characters hung out with only because they felt sorry for her, not because they were really friends, or because she had anything to do with the plot. My interest waned in the penultimate scene, as Yara chewed and read aloud, I found my mind start to wander momentarily.
A good double feature can be made with this film and the simultaneously released, Unfriended.
