I saw the show... seems questionable compared to the other Ghosthunters show.
Ghosthunters International is GHI. Ghosthunters is TAPS.
TAPS seems better than GHI.
GHI seems to use methods that are erratic and not stable. For instance, one woman is holding a camera with a flashlight. Suddenly, she claims to have seen a shadow moving around. Well, she's holding the light with her hand and she's obviously moving and twitching constantly. Of course, a shadow is gonna appear somewhere!
Of course, I often watches Ghost Hunters, Ghost Hunters International, and Ghost Adventures (on Travel Channel). Why not try to watch Ghost Adventures on 9 pm Fridays on The Travel Channel? This Friday, Zak's team will investigate Gettysburg because that place is very haunted. Ghost Adventures are more active than Ghost Hunters.
