Ghost Hunters

So here's my snarky synopsis of this little gem and its various TV imitators.  Very often the founding investigators are at their day jobs as Roto-Rooter plumbers when they get a call to go on an investigation.  Luckily and by sheer coincidence there are cameras and sound equipment right there when they get the calls.  They are always wrapping up their plumbing work so that they can appear at the ghost investigation office shortly.  This too is coincidental.  In spite of the TV work, which I assume is fairly lucrative, especially considering the spinoffs like  "International," and "Academy," and I also assume sales from t-shirts and magazines since they are subliminally shown always, the founders are still plumbers. Next they appear driving to the scene of their next investigation.  As they get close to the scene of their next paranormal investigation, they always ask the woman who has manned the phones at their headquarters for more information about the reports of "activity."  You mean they have driven hundreds or even thousands of miles before having all the information?  Wow.  Luckily and by concidence too, that also brings the viewers up to date on the reports.  Then they visit the creepy place,introduce themselves to the owner, say "we're here to help (help what? help themselves to a great contract to appear on cable?), listen to the reports, and set up their equipment.  One of their lead investigators is covered in tattoos, is deathly afraid of spiders, and is also afraid to fly.  Afraid of spiders but not afraid of ghosts?  Holy mackerel.  In almost every one of the creepy places there are reports of a lady dressed in white who floats down the stairs.  Except when they went to Florida to investigate a Cuban club.  They had a lady dressed in white but she was wearing red shoes.  After all she was the spirit of a Cuban lady and apparently ethnic stereotypes exist even in the next world.  The investigators use thermal imaging cameras, emf detectors, and various recording devices.  It's all quite sophisticated.  After viewing tapes of what they did, they report back to the owners of the creepy places.  They sit at a table and the heavy guy always says, "You know what we did.  We came here, listened to the reports of activity, set up our equipment..........."  It never varies.  By the way, they often come upon "cold spots," in the course of their investigations.  One of the investigators always explains that "there is a theory out there that when one of these spirits wants to manifest itself, it needs energy..." and apparently creates cold spots, drains batteries of their power, etc.  I have several questions.  What does it mean to say there is a theory out there?  Out where?  Whose theory?  If a spirit needs energy to manifest itself, and they got it, then why haven't they manifested?  Is there a theory out there on that? Anyway, back to the table where the investigators are reporting.  They always have a computer, then we see them leave the places, no computer.  What happened to the computer?  Maybe the spirits took it.  So that they could manifest themselves.  That's my theory.  The investigators always express their hope that they can get back to the creepy place one day.  They are always invited to come back, but they hardly ever do.  Then we see the lead guys back in their vans, congratulating each other on a great investigation and fist bumping.
I think any self-respecting spirit would steer far clear of this stuff.
