TNT's first dramatic series, Bull is set in the world of high-powered finance and IPOs. Robert "the Kaiser" Roberts (Donald Moffat) is the head of a business empire, and cannot comprehend why his identically named and ethically minded grandson (George Newbern) wants to break away and start his own firm. Bull's ensemble cast features turns by Stanley Tucci as a dodgy operator, and Ryan O'Neal as the Kaiser's errant son. ~ Rebecca Flint Marx, Rovi
