Full disclosure: I love Zak Bagans and Ghost Adventures.
The host, Zak, is endearing and kind to others but becomes angry and dramatic around ghosts and ghost activity. I live for ghosts caught on camera, and the show has some of the best audio and video recordings that send chills up my spine. I also like that the episodes are thoughtful in their storytelling about the locations they visit, with their mix of spookiness and a reverence for the past and the spirit world.
Watching the movie Grave Encounters, I was immediately connected to the characters because they were a parody of the Ghost Adventures crew, and I felt like I already knew who they were. I love jump scares and all things ghosts, so I truly enjoyed the movie. I was particularly surprised by the turn of events in the last quarter. It was not what I was expecting, but it was everything I never knew I wanted! Grave Encounters is one of a few horror movies that I liked from beginning to end, and on multiple viewings.
A sequel was made that I did not like as much, but I would recommend it for the purists who want to see it for themselves.
The Vicious Brothers. Grave Encounters, Tribeca Film, 2011.
