If you just did a horror tone throughout an entire movie you almost, as an audience, can get a little bit used to it. But if you're laughing one minute and, you know, somebody's doing something quite horrific the next minute, it's a little more shocking.
I mean, I'd love to have a private jet - I know people who fly by private jet all the time... I've hitched a ride a few times and it is not overrated at all; it's a great way to travel!
