Watcher's pace can sometimes feel haphazard or arbitrary, but the strong finale makes it all worthwhile. The Watcher builds slowly, spending plenty of time emphasizing the main character's isolation and loneliness. Each passing moment of this slow burn accentuates the paranoia of being watched. Maika Monroe proves her horror chops once again with Watcher, as she has before with movies like It Follows and The Guest. I wanted to give this movie a better rating than 3/5 but the gradual crawling pace of the film, although intentional and effective in creating tension, had me looking at my phone out of bordem. The last 20 minutes of the movie are intense and pay off nicely, though, and make it worth hanging around until the end. As a horror fan, I enjoyed Watcher and would recommend giving it a shot, but don't set your expectations high.
