I'm selective. I enjoy shows like "The Amazing Race" and "Shark Tank". I also like "The Apprentice" when the contestants are unknowns and not washed up has-been celebs trying to keep their faces before the public.
The bottom line with these shows is that they make me think and role play. I'm not into the dating shows or the real housewives or American Idol or Dancing With The Stars or all their assorted spin-offs.
But even though they are staged to some degree, I enjoy the ones that make you think through situations rather than just vege and gawk.
The reason these shows sell is the low production costs. You don't have to pay for script-writers or tempermental actors (see Charlie Sheen, who can be both temper and mental). Even with some big prizes, the shows are cheaper than another CSI or sitcom. And enough people watch them to make a profit.
I miss the old Mile High Stadium.
