“The Dinner Party” (*1/2 out of four) was a bloody mess about a wealthy but deeply eccentric surgeon (Bill Sage) who invites a struggling playwright (Mike Mayhall) and his wife (Allie Hart) to their home for dinner with a promise to bankroll his latest play but have deeper/darker intentions and they soon struggle to psychologically and physically survive. Writer-director Miles Doleac has some flashes of style and macabre wit but it’s gory and mean enough to give anyone indigestion. Hardly a “party” worth attending, especially at nearly two hours.
