I was very reluctant to watch this show because of the name, "Portals to Hell". It kind of gives the impression that this show is about them trying to prove there is a doorway to hell in these locations which isn't actually an accurate assessment of what they're doing. They're going in with the intention of investigating these places like any other "ghost hunting" show.
What I like about this show is that they let you see and kind of get to know the behind-the-scenes crew. They actually show if one of the crew has an encounter while at a location which helps to add validation to a haunting. I also like that Jack Osbourne seems to have a skeptical nature which is nice in comparison to some other shows where every noise and every sight is a "demon".
I don't like that they had Cindy Kaza on as a "psychic medium". I've seen her in other things and I don't believe she's a psychic or a medium. When she joined them at Bobby Mackey's, the information she gave them was stuff that has been well documented in other ghost hunting shows, specifically Ghost Adventures, and the haunted tour guide that took Jack around at the beginning of the episode mentioned the one and only documented death was a man who got in a fight and basically dropped dead from a blow to his head. Cindy could have EASILY researched that. And I'm sorry but "automatic writing" sounds like a bunch of BS and it didn't escape my notice that you didn't really get to see what she was writing.
Suffice to say, that Portals to Hell isn't really a unique concept because just about every type of ghost hunting show that could be done, has been done. But if you're like me and like to watch these shows to see what kind of evidence people get, then give this a shot.
