Two high school girls leave mean comments on a dead girl’s Facebook page. The comments are seriously unappreciated by the dead girl’s vengeful ghost.
This was actually better than I expected it to be, mostly because of Ana Coto’s performance. It has a “I Know What You Did Last Summer” vibe, updated to the social media era (and even starring YouTube personality Logan Paul), and actually makes good use of social media technology (including one quietly unsettling use of facial recognition tagging in a Facebook picture). I watched it while working, so it only got about half my brain’s attention, but that half enjoyed the ride.
