Phantom of the Mall: Eric’s Revenge (1989)
It’s exactly what you think it is: Phantom of the Opera except ever so slightly rearranged to be a slasher that takes place at a mall—where a shadowy figure creeps around, stalking a pretty employee while engineering other delightful unpleasantries. Yep, that’s an eyeball in your fro-yo. Watch on Shudder.
