SEASON PREMIERE: The first two installments of Season 2 are shown tonight, featuring such physically rewarding, or punishing, games as “Blindfolded Musical Chairs.” Ellen DeGeneres presides, gleefully, over a gauntlet of supersize versions of the playful games seen on her daytime talk show. And she seems to be having such fun, I wouldn’t be surprised if Ellen’s Game of Games outlasts its long-running parent program.
