BEST RTV TRAILERS AND PREVIEWS ON TV

Now that you are underway in creating your own reality television show and a trailer or short preview to go along with it, I want you to start evaluating RTV trailers/previews on the air/online now. Post a link to a preview or trailer that you find especially successful, intriguing, funny, scary, full of attention grabbing drama, etc. Along with the link to a video clip, I'd like for you to briefly analyze the trailer/preview. What makes it so successful? What tactics does it employ to grab the audience's attention? Drama, comedy, emotional appeal? What makes you want to watch more? Does it use interesting characters to grab your attention, profile people you want to know more about? Does it flash around attractive men and women? good food? a big fight? Does it seem like it has an interesting plot? How does it advertise/sell the series?
