The acting and writing worked well. The cinematography and editing had me a bit confused. For example, near the beginning when the protagonist was talking to the janitor, I found it difficult to keep track of what was going on. The screen direction changed a lot, which may have been an intentional choice to try to make the scene more unnerving. I personally found it disorienting. In nondialogue scenes, it worked fine, but was still a bit too high. (Editor gets props for the transition at 1:10)
Really good cinematography and editing, but the story was very cliché. Acting was decent enough because it had good direction.
