Aside from some mediocre voice acting and the obvious bevel filter, this was really well-done, and I especially liked the outside landscape and how complete it looked. The keyhole part was fucking tense as shit - I was expecting a scare. I found it really funny that the guy didn't do anything stupid, contrary to virtually every horror movie ever, but at the same time the unsatisfying nature of it was also refreshing.
I also think it's kind of odd that the lady told him not to go into that room when nobody ever disturbs another room in a hotel or as a guest in someone else's house. Most likely the guy would have left that room be even if nothing had been said about it. Even then, there's no reason the lady couldn't have told the full story from the beginning. Oh well.
