I have DirecTV which didn't have the PPV, but if had been available to me for a reasonable price, I probably would have bought it.
Why? I guess mostly curiosity at seeing extreme muscular development. And, yes, there's a bit of a "freak show" aspect to it as well, especially these days.
And that's also the reason I would consider not buying it: The physiques are just grotesque these days. People have always said that about bodybuilders, and I used to disagree with them in, say, the Lee Haney era, but now I don't see how it's a subject for debate. The distended abdomens are gruesome.
And women's bodybuilding is a total freak show and is completely dead. The Ms. Olympia was apparently held at the expo center this year instead of on the main stage. I was curious to see if they actually scored down women that were too big, but I can't find the results anywhere.
