Battlestar Galactica finally goes flying off the deep end with its WTF-errific third season finale, "Crossroads," in which Ron Moore (again) blows his show up on a whim, characters fall apart (physically, emotionally, and psychologically), the dead return to the living, Tory neglects to comb her hair, and everybody gets an old song stuck in their heads. It's pretty much crazytown. Elsewhere, for the third year in a row we turn to Mad Men to get through the summer. We kick off the fourth season with awkward divorce holidays, on-the-nose prostitutes, worked-shoot grocery store fistfights, and Don getting a tough lesson in managing his "Public Relations."
