This week, Bravo premiered a new reality show — the travel-themed First Class All the Way — and wraps up its second season of another, Top Design. The network really seems to have the formula down for its reality shows: They're either competitions (Project Runway, Top Chef); shows that feature a particular eccentric expert in some field (Work Out, Flipping Out, even Kathy Griffin: My Life on the D-List); or one of the Real Housewives series. And then, of course, there's the granddaddy of them all: Queer Eye for the Straight Guy. This successful formula even recently got a network executive a big profile in the New York Times. Looking back over the years, which of Bravo's many reality shows is your favorite?
