SERIES RETURN: This is cycle number 30 for this granddaddy of modern reality competition shows, and it arrives with a new twist. This time there are three tribes, and they’re divided along class lines. There’s “White Collar,” “Blue Collar,” and the noncomformist “No Collar.” (No shoes? No shirt? You’re over there, on team three.) There’s no “One Percenter” or “CEO” team, which really would have been interesting – but I guess Survivor couldn’t pay them enough.
