Book excerpt: What kind of collection could possibly find common ground among The Son of Kong, Platoon, and Pink Flamingos? What kind of fevered minds could conceive of such a list? What are the unheard-of qualities that tie them all together?br Once the B movie was the Hollywood stepchild, the underbelly of the double feature. Today it is a more inclusive category, embracing films that fall outside the mainstream by dint of their budgets, their visions, their grit, and occasionally -- sometimes essentially -- their lack of what the culture cops call "good taste".br The B List are offbeat, unpredictable, and decidedly idiosyncratic. And that's why we love them.
