I love this show, and it's coming back for another season.
There is something very amusing about seeing people almost shit their pants over some of these things. It's a Candid Camera sort of thing, but with a Sci-Fi/Horror twist. Sometimes, they suck. Sometimes, they're great.
Just the concept of putting someone in these positions and scaring the shit out of them is delightful to me. And I would find it HILARIOUS if they told someone their parents died in a car crash, but it would only fit in with the show if they came back as zombies and tried to each their child. That would be even more awesome.
