Sorry - I have never been able to watch it, or any show like it. No "dancing with the Stars" or "America's Got Talent" for me.
I find most of television to be excruciatingly boring these days.
The only things I like are a few good dramas -
Once Upon a Time
Sons of Anarchy
And I will admit I can get sucked into shows like "The Bachelor" or "Hell's Kitchen" - but they all got old for me when I realized how "rigged" they are.
