Last night, Expedition Impossible, the latest competition reality show debuted and this one bears some remarkable similarities to The Amazing Race. It's from the mind of Mark Burnett, the reality mega-producer who brought us the granddaddy of competitive reality shows, Survivor. He also brought us Pirate Master, but he'd probably prefer that we forget about that one. Anyway, I was excited because I loved Burnett's early series Eco-Challenge (though the production values lacked some sparkle, the actual physicality of the show was appreciated) and hoped that this would be a modern version of that. In some ways it is, but in other ways, it also liberally borrows from TAR. Here's how to keep these shows straight and figure out which is worth your time if the majority of your life isn't spent watching reality shows like mine is.
