I hope the contestants on “Traitors” received therapy after their time on the reality competition show. This game is diabolical and I can’t stop watching. In the first season, which debuted last year on Peacock, 20 players, consisting of reality TV stars and non-TV stars, convene in a Scottish castle alongside host Alan Cumming to play a murder mystery game. They must lie their faces off to each other and figure out who’s a faithful and who’s a traitor. — Jennifer Mulson, The Gazette
