I rented The Mothman Prophecies because I enjoy watching creepy supernatural stuff when there's no one around but my cat. (Mild Spoilers below.)
The main character (the one played by Richard Gere) is pretty dumb. I mean, I thought he was smarter than the average horror protagonist when he got creeped out by the phone call where Cold knew everything, so he turned off the lights and closed the shutters (where a normal person would not want to sit in a dark hotel room and listen to that creepy voice).
But he thinks the chemical plant is going to blow up, so he accosts the Governor and asks him to close the place down. He's ranting and raving like a complete madman, and gets escorted away When if he really wanted to shut the place down he could have just called in a bomb threat (what's really amazing to me is that they assume he's heard a bomb threat, call one in, and he says "I didn't get a bomb threat!" and torpedoes the option they'd take him seriously). Yes, he'd have gotten in trouble if he got caught phoning in a threat. It's illegal, he'd have been arrested. But he wouldn't look completely fucking insane, and he'd have accomplished what he wanted.
(I haven't read the book, so I don't know if John Keel actually acted like this, but I know they changed a whole bunch of stuff so I'm going to assume that any character behavior is the fault of the writers.)
And it makes me worry about the heroes in these supernatural thrillers. They're supposed to seem like rational people, so that we can be drawn into the story. It's not supposed to be someone we can write off as a nut, but someone like us who is experiencing this stuff. Makes it more believable.
But damned if every time we get to the point where the hero is trying to get the police or the government on their side to prevent a disaster, they go the route of looking like a complete lunatic and risk getting committed for their trouble. And they know, going in, that there is no way in hell that the authorities will take them seriously. But they try anyway, and that's supposed to be the heroic part. Except they just seem stupid to me, because there are usually sneakier and more effective ways to accomplish that objective in today's society.
And don't give me "we don't want our hero to lie." If he's really so fucking sure that a whole bunch of people are going to die, he should lie if he has a better chance of being believed and getting the place evacuated. Even if he's wrong.
