My issue is less with "Ghost Hunters"(which I see more as people seeking to entertain others with spooky stories) and more with the "Paranormal Investigators".
See, when someone claims to be an investigator you would think that they have a certain skill set, a method, a professionalism towards investigation and the solving of a case.
Yet most of said "paranormal investigators" look more like people trying out a hobby rather than actual professionals that do know what they're doing.
None of them do actual research of places, history and people aside the bare minimum needed to tell a story.
None of them are(or have in their group) people with actual skills to deal with entities(even those that claim to be mediums usually seem to be poor oner since they themselves do not seem to go prepared to defend themselves if needed be) and if necessary the rare human unknowns(homeless people, drug addicts, criminals, etc.) or even beasts.
No decent preparation aside the usual "P.I. gadget" that, as far as I've seen, can be the same as "nothing" or not be used properly.
So in the end, they're everything but investigators.
Seriously, never saw a decently professional and prepared group, usually it is a "Scooby Doo group" of sorts that pretend to be legit investigators.I think most of them actually wouldn't know how to deal with a being following them home or even might make things more difficult for those that live in haunted houses.
Exactly because they lack the knowledge, experience and professionalism.
