Let's begin with Paranormal State http://www.aetv.com/paranormal-state/ which airs on A&E. I have watched this show several times. It failed to grab my interest. The main issue I had was the first few episodes I watched they seemed to dwell on people being haunted by demons. The trailers even suggested that the team itself was being threatened by a demon that was following team leader Ryan Buell. Setting the drama for "will the demon get Ryan in the next episode?" type of feel. Every investigation I saw the "client" was haunted. They seemed to go in with the presumption that they would and did find a ghost or demon. Not much in the way of debunking, I hope they get better. The new season starts Dec.15
A newcomer to the game is Ghost Lab http://dsc.discovery.com/tv/ghost-lab/ghost-lab.html on the Discovery Channel Tuesdays at 10 pm PT/ET. Two brothers from Texas with a mobile high tech lab they tow around the country doing investigations. The cast is likable and they view things with a skeptical eye not likely to say some place is haunted without evidence. I've enjoyed this show even if it does seem a little commercialized. The show is narrated by Discovery Channel uber-narrator Mike Rowe, whose voice is instantly identifiable and lends an air of credibility like a endorsement from an old friend. It's well produced and still in it's early stages time will tell if it has the chops to stay.
Also new to the TV air waves it Extreme Paranormal http://www.aetv.com/extreme-paranormal/ also on A&E. The team has a regular radio gig where they host a talk show about the paranormal. On their days off they investigate "haunted" places. Their methods are not your typical wait and see what happens investigations. No, they try to recreate events that lead to the death of the person haunting the location. They will also perform rituals to evoke, provoke or summon spirits. It's an interesting show and will suck you in. If for no other reason than to see what these guys will do next. Since starting this blog, this has gone to the other side and been cancelled
Of course there is the venerable Ghost Hunter and Ghost Hunters International or GHI as they like to refer to it. Grant and Jason are like old friends and have gotten more likely to call a place "haunted". In the early days Jason had to just about see a full body apparition before he would use the "H" word. But they still do their best to debunk the hauntings. Ghost Hunters and GHI air on SYFY and www.syfy.com/ghosthunters
Last but not least is Ghost Adventures is a weekly American paranormal television series that premiered on October 17, 2008 on the Travel Channel. Currently produced by MY-Tupelo Entertainment (a merger of MY Entertainment and Tupelo-Honey Productions), the program follows and stars ghost hunters Zak Bagans, Nick Groff, and Aaron Goodwin, as they investigate locations that are reported to be haunted. Hosted and narrated by Bagans, the show initially airs new episodes on Fridays at 9 p.m. Eastern Time on the Travel Channel. The tagline of the series is: "Can you handle the lockdown?"
So check them out and don't worry about that sound down the hall, it's probably just the wind.
