There was already at least one violent, drunken incident during filming,so expect the show to return in top form.

ABC, Mondays at 10 p.m., starting August 9
A unique twist on the dating format. The show puts prospective daters together in a dark room to get to know each other before they meet in the light. Seeing the contestant's reactions once their dates are revealed lets viewers know just how shallow (or not) people can actually be.
