I agree with the overall sentiment that this years show is not as good as last years. It's not just about BBQ and it's got a game/reality show format. What I see is they have added two real twists beyond the "being voted off the island" part. Those 2 are the requirement to cook something unusual, like rattlesnake and the addition of a side dish requirement.
Looking at the product (i.e. the show) more generally, someone who is a BBQ "Pitmaster" should be able to competently cook different kinds of things beyond pork, chicken, and beef. So in a way I get that part of it. However, if there was a part of the show I would like them to lose, this would be it for many of the reasons people say here (how do you judge rattlesnake if you've never had it?).
I don't mind the idea of a side dish because, let's face it, more than likely you're going to get top-notch BBQ from the majority of the entrants. I think the side dish is a good way to *fairly* choose between two very close candidates. Make sense?
