Ewww, please no. If I ever see those people again I'll spit. It's not their fault, I just don't like that they're randomly famous for winning Survivor.
I think reality shows should act like the other shows don't exist. Survivor All-Stars should have Survivor contestants, TAR All-Stars, TAR people.
On the other hand, the most annoying thing about Rob and Amber was how it made the race all about them, and that wasn't their fault - the other teams let it get to them and I think the producers played it up. TAR All-Stars would maybe not have that since they'd all have been on before.
I don't want to see Rob or Amber again, either. I was tired of them on Survivor and then they came back. Then they played it up on every talk show for what seemed like years. And then it was on to T-A-R aka "The Amber and Rob" show. Enough already.
