Looks terrible.
Obviously I haven't watched the film yet so I can't make a proper judgement, but it just looks like a second-rate Unfriended rip-off. Ignoring the comparison between that film, the trailer for "Friend Request" has got to be one of the most boring cliche-ridden trailers i've ever come across.
Why haven't people realised that obnoxiously loud sounds and stupid jump-scares do not make a film scary? If you want to see a truly unsettling film released this year, go and check out "The Witch".
