My wife picked up a DVD not long ago which happened to be the original  Ghost Adventures documentary; taking place long before Zak Bagans discovered the gym.

It was impressive to see that their film-making style was very much evident back then and certainly helps in creating the right atmosphere for the shows that followed.

The big ticket item in this documentary is saved until the end with what looks like physical evidence of a poltergeist. No matter what your beliefs are on the subject of ghosts, it’s an impressive sequence that in the very least makes you wonder how that was even possible.
