Derivative and poorly executed.

Rating: 2/10 (17 February 2015)

I'm amazed that some reviews state that this film is 'original' or 'unique'. I can only assume that these reviews are written by people who don't watch films!
A tip for those of you who are thinking of going to see 'It Follows': Save your money and revisit 'Ringu' by Hideo Nakata or even 'Night of the Demon' by Jacques Tourneur. Two vastly superior films with broadly the same plot, except without sex as the MacGuffin for curse transfer.
There are so many plot holes and the premise is so illogical and poorly set up that the viewer never invests in the narrative other than at the most superficial level.
The only true horror in this film is the soundtrack, which sounds as if the composer had been given a box of synthesizers for Christmas and didn't really know how they worked.
As for being 'the future of horror' - I sincerely hope not!
