That's funny, because Ghost Adventures was one of the ones I was thinking of explicitly. They ALWAYS find multiple EVPs, & frequently find "relevent" ones, EM spikes, temperature drops, etc. Now, keep in mind, there's a difference between what you & I consider evidence of ghosts & what the show is claiming. True, they only get something that raises my eyebrows every few episodes, but their claim is that they find something good every single time. In fact, they in specific have apparently gotten this observation before, because in one of the episodes, they handwave that it's because they investigate for 12 hours straight.
Other shows I've watched recently that fit a similar "ghost investigators" theme are Dead Files & Paranormal State. I can't think of any others at the moment. Speaking of, something I may have been vague upon earlier is that this is a certain type of paranormal show--I'm not commenting on anything relating to UFOlogy, anything which actually uses debunking tactics, anything that is primarily interviews, etc.
Mayhap. I wouldn't mind continuing this discussion. Though I wouldn't lose sleep if it died either.
