A Public Service Announcement

Rating: 6/10 (27 October 2017)

"It Follows" is a a low budget yet decent film about a being/entity/presence that quite literally follows its victim.
A young woman gets intimate with a guy only to have him violently tell her, "tag, you're it", in a sense. Maybe he didn't say those exact words, but he essentially told her that now he has freed himself and that she will be followed by some unknown malevolent life force and it will continue to follow her until it has killed her. That is, unless she can find someone else to pass it on to.
The movie then takes us through some tense moments with a few jump scares. The story line is OK as well as the acting.
What I can't figure out though is: is this movie a public service announcement for abstinence or for sleeping with as many people as you can? Makes you go "hmmmmm?"
