I find these endless UFO and ghost shows and films interesting. Not because there are any UFOs or ghosts but because of the people who believe in them to the point of obsession (and the con men and women who prey upon the true believers) and how often reasonable and intelligent people can avoid accepting the obvious conclusion that there are no such things. An interesting insight into human beings. And since these UFO and ghost-related shows play endlessly on various cable channels, they must be wildly popular (and cheap to make). I get a kick out of those ghost hunters who stumble around in the dark yelling "did you hear that"? In this day and age when almost every event, including sudden, unexpected events, are captured on phone or security cameras, like a meteor crashing in Russia, it should have put an end to the UFO and ghost claims because they are never confirmed on the film but they just seem to go on and on.
