"Ghost Hunters" - what do you think?

Thanks to my mom's interest in the paranormal, I recently started watching the Sci-Fi Channel series "Ghost Hunters." Basically, it's a reality show in which a camera crew follows a group of professional ghost hunters from Rhode Island called the Atlantic Paranormal Society (their website is here: http://www.the-atlantic-paranormal-society.com/) as they investigate reports of paranormal activity throughout the country. They generally set out to debunk any claims they receive, and often find logical or scientific explanations for the stories they're told. However, every once in a while, they manage to capture video or audio that they find to be totally unexplainable, such as a clear disembodied voice or footage of a full-bodied apparition.

I've tried talking about this show to a couple people; one dismissed it as fakery (though the show claims to be 100% legitimate), and another immediately said there was no such thing as ghosts and refused to watch it. (Sounds like a chicken to me...) I personally think that it is in fact legit, because they don't *always* find something amazing; several episodes have included locations that came up empty, and at least one saw an inhabitant of a supposedly haunted hotel attempt to fool the TAPS crew (and fail) by tampering with their camera. But when they do find something big, I'm not afraid to admit that it's scary as hell. :-)

I do, however. find some of the show's 'scare tactics' to be cheesy - the 'on this episode' and 'on the next episode' previews are usually heavily manipulated, cutting and pasting footage and dialogue in order to lead one to believe that something absolutely outrageous happens; and the second season especially made totally unnecessary use of "The Ring"-type subliminal images and sounds that popped up whenever a scene started to get quiet. But those two complaints aside, what we see does appear to be real, and does shed a horrific light on what could possibly be sharing this planet with us.

What do you think? Do you think that the show is staged for entertainment value, or do you think that the ghosts that they sometimes see and hear (and then present to us) are legitimate?
