Betrayal seems to fall into the very special category of shows I lovingly dub Cheese Grater TV. The reasoning is simple. I would rather rub a cheese grater up and down my arm than sit and watch this. My only comfort is that Mary and Cat both have equally awful shows on their dockets, so I am not suffering alone . . . or in silence.
Betrayal has a very simple premise--it's Romeo and Juliet, with a sexy, unhappy marriage spin. Married girl meets married boy in fair Chicago, where we lay our scene. Both are miserable in their respective marriages, but are still married to their unsatisfying partners, a truly difficult premise to believe in an age of drive-thru divorce. I can only guess that their noble resolve to stick-it-out is designed to make them sympathetic.
Tell me if this sounds familiar. Character feels neglected because he/she married a successful lawyer/doctor/politician/cop/etc., usually once his/her spouse was established in their field. Character begins to feel the strains of spouse's time consuming and stressful career and villainizes spouse for having said career. This resentment translates as justification for cheating.
I suppose Betrayal is original in that the cheating partner is our protagonist, likely in a desperate move by the network to make the character sympathetic. Perhaps Sara is sympathetic to the 50 Shades of Grey crowd, but cheating rarely appeals to me as anything more than sensationalizing and glamorizing a tragic failing of trust.
I can't help but extrapolate the entire first season from this preview. The two leads are going to have a chemistry-barren affair that comes to light as does everything during tawdry legal battles. One will stay with their spouse (probably Sara, 'cause kids) while the other leaves, adding pressure to the situation. Season finale is a sexy reunion in an inappropriately public place after the affair is called off.
Who am I kidding? It won't last until Christmas.
