The Korean War had ended, but the creators of the hit show M*A*S*H, one of the most successful television shows of all time, just couldn’t walk away. Like the Grey’s Anatomy spin-off Private Practice — whose second season premieres tonight — AfterMASH took a main character out of a high-pressure medical situation and placed that person into … a significantly less vital setting. Yanked from the cauldron of war, Colonel Potter, Sergeant Klinger and Father Mulcahy end up at a veterans’ hospital. Scintillating. A well-received first season was followed by a disastrous second one when AfterMASH was placed against The A-Team. Then it was canceled.
