Ok. My comment on American Chopper was a joke, but I think I am going to go back there. I agree alot with what Papa Bear said about Steve Irwin and that type of show.
I am not in the biz, I am a lay person, but I know a little about what people watch, and why. I loved the trailer, at least the diving shots, and I will watch all 13 shows and hope for a season 2. So consider this some brainstorming, constructive critizism, free advice, whatever you like. I am not trying to be mean, jut putting some ideas out there. Take it for what it is worth.
Standing at an airport, or under palm trees waxing on about the show, boring as heck. And the young hip crowd you want is not going to tune into that. Music? Designed to set a mood. Nobody tunes in for the tunes. There are channels like VH-1 for that. I would suggest instead of putting your hosts in an airport parking lot, you should have had them on cliffs looking out over a rough surf, near some blowholes getting drenched. It looks cooler. Have them treading water with the wild dolphins popping in and out of frame. Or even walkiing down the beach passing hot chicks in bikinis and the local kids with their skimboards in the background. Static shots don't hook people. Action does. Your hosts are young, in shape and good looking, use that, get them moving.
IMO even the simplest walkie talkie scene is better than the static shot. Unless you have something really interesting in the background, like lions on a kill. An airport? Not so much.
American Chopper does better than the other motorcycle build shows because of the action, not the bikes.
Just my thoughts. Good luck...
