Us Rating: ***1/2

The briskly paced reality show -- in which contestants pitch their fledgling business ideas to top entrepreneurs who are looking to invest -- gets a boost in its season premiere when cocky billionaire Mark Cuban joins the panel. The biz whizzes have a diverse crop on their hands, as the concepts range from bright (an online toy rental club) to goofy (an alarm clock that cooks bacon!). And the investors' tense wheeling-and-dealing gives Shark bite. (ABC, 8 P.M.)
