Anon is a decent watch for 2/3 of its running time. If that sounds like a decent Netflix watch to you, have at it.
Your time is better spent watching infomercial .gifs of people overreacting to non-problems than watching The Clapper.
Jennifer’s Body is an ineffective slasher film. It is not worth watching.
Mean Girls is one of the best high school movies of all time. It’s hilarious and you need to watch it.
