It's not surprising. Often ideas promoted by Hollywood are found to be largely false. Think of the successful American cop shows and the many cliches, conventions and stereotypes they rely on. One thing that real law enforcement officers must find consistently laughable is the speed with which fictional detectives solve crimes and apprehend the criminals.
Sure, there's more than a grain of truth in these shows, but that becomes heavily distorted by the need to tell a compelling story and be entertaining. I think the same could be said of the cougar phenomenon.
