Mark Dujsik’s review published on Letterboxd :
Jerry Rapp's screenplay for Looking Glass is an exercise in seeing how many creepy elements can be added to a story without finding a way to connect them. Surely, there's some underlying conspiracy or basic, small-town suspicion that ties the movie's various, creepy elements together, but the connections that are overtly made here seem like an afterthought. It's an atmospheric movie, to be sure—filled with unseemly things happening behind closed doors, characters whose motives are mostly unclear but clearly hostile, and a protagonist who finds himself drawn to the darker side of whatever is happening.
