Rating: 4/10 (9 August 2015)

The idea of a sexually-transmitted curse is very original, plus the soundtrack and the 80'ish atmosphere makes it not the the average horror movie that Hollywood has us used to (https://www.youtube.com/watch?v=zz6KOsePEHs).
Nonetheless, there are many mistakes in the plot. Some basic unanswered questions that are: Why didn't they go to school? where are their parents? how did the ex-boyfriend know so much about the curse? why did the ex-boyfriend do that stupid "kidnapping"?
It would have been better if this group of friends discovered more and more about the curse by accident, like relating the moment when Jay started seen the thing (her sexual encounter with her boyfriend) with an infidelity of her boyfriend. That way they would have learned how the curse operates and is passed around. The plan to get rid of it could have consisted on passing the curse to someone undesirable, like one of the bullies from school.
