Hell House LLC.

This film is very well done and frankly terrifying, a must-see modern classic of the found footage genre.
You may be so frightened you have to turn on the lights, we warned you!
The film has a great score, jump scares, and creepy set, but the slowly building tension is the standout.
It’s rare for a film in this genre to do such a great job building attachment to the characters.
Maybe don’t watch before you visit a haunted house this October, or maybe do? Hahaha
Like most found footage films, it features a cast of unnoteworthy actors.
