These shows are all the same formula:
1) A sad sack scientist who paid attention in school and earned an advanced degree in some unrelated field surrounded by a group of infinitely credulous actors who are frightened of their own shadows and attribute the most banal things to aliens or ghosts or whatever.
2) Investigations that only take place at night because the aliens or ghosts or whatever apparently have day jobs.
3) An exotic location that has been visited by a jillion paranormal investigators in previous series.
4) They interview several sorry individuals suffering from paranoid delusions who should be encouraged to seek the services of a mental health professional.
5) The actors act scared of every noise and attribute every flicker of light in sky or glimpse of something moving in the woods as definitive proof of ghosts. The other films crews working in the same area use that same evidence as proof of Bigfoot and aliens and time travelers and ancient aliens plus whatever else they can make into an episode.
6) Though the area has been the subject of intense scrutiny by other investigators for decades, this investigation lasts a couple of days because that's all the budget they have.
7) They find nothing, which they take as proof positive of the aliens or ghosts or whatever they were looking after.
8) The scientist, ridiculed and ignored the entire episode, is coerced into a voice over the closing credits to the effect that it is still a mystery.
9) Filming stops and everyone high fives one another and toasts the gullible dupes that comprise their audience.
Five stars for having the stereotypical infinitely credulous cast member, the one convinced a Big Mac is proof of ancient alien Bigfoot ghost time travelers, as a male instead of the more typical female actor. Five more stars for the laughs. Minus five stars for going to Roswell. Roswell?! Five stars.
