One reviewer is either terribly confused or trolling by stating that this film is in any way about zombies. Surprise, No Zombies!
This is about high school seniors who find a deceased former classmates social profile and leave some nasty comments on it. Then each of them is haunted by a malicious spirit and discover that their cruel remarks cannot be apologized for nor "taken back".
The storyline seems cliched and unimaginative, even so, it could have been better written.
Much of the acting is wooden though it's not the worst of 2017. The finished product is reads as a campy B-flick potpourri inspired by similar themes and it is unforgivably predicable.
This one seems like it's the work of a film student/ first-timer and was hurriedly completed on a shoe-string budget. Many great films have been produced under them same constraints, but this isn't one of them.
I agree with another reviewer that says this movie would appeal greatest to very bored teen girls.
