I'm not familiar with that show
If he likes the paranormal...he should probably watch a show where they aren't faking evidence and pretty much disrespecting the dead -- and making a laughing stock of actual investigators - at every turn.
If you're going to watch a show about the paranormal, you should consider something like A Haunting - the show that aired on the Discovery Channel. It's more interesting and much more entertaining. I don't doubt that some things have been exaggerated for rating but overall most of the stories that can be backed with interview evidence and other sources show that the creators and writers did their best to make a show that was mostly factual.
The Moon River Brewery was good. As Nick was leaning against a pool table, a black mist appeared behind him. His eyes were as red as a fire truck., and he was in a trance. That was pretty cool. I live down the street from the Ghost Adventures main office here in Las Vega$ I have never been in there, but if they sold memorabilia, I would definitely go there, but they don't.
I suggest showing him the "Lizzie Borden House" Where they go through the place she killed her mother and father. It's a very cool episode, and also includes a Documentary throughout the touring of who she was, what she did, and what happened in the place of the murders.
Bobby Mackey music world is pretty damn good!
My boyfriend hasn't seen ghost adventures yet but is really into paranormal. Which is the best ghost adventures episode to show him as it will be the first one?
