A courtroom drama set firmly in America's post-O.J. legal system, Fox's new ``Justice'' is slick, fast-paced and stylish, with enough twists to separate it from the glut of shows in its genre. But it's also one of the most extraordinarily cynical shows to come along in some time. If the premiere (9 p.m. Wednesday, Chs. 2, 35) is any indication, the creators have their work cut out for them if we're going to warm up to their chilly, ambitious, borderline-amoral lead characters. Trott, Nicholson, Tuller & Graves is one of those ``dream teams'' that specializes in high-profile criminal cases (which on TV seem to exist only in Los Angeles). Ron Trott (played with great relish by Victor Garber of ``Alias'') is so egotistical that juries can't stand him, but he's a wiz at manipulating the media.
