MINISERIES MARATHON: If you’re interested in the O.J. Simpson saga, you can make a day of it today. A full day. Beginning at 2 p.m. ET, FX is repeating, in its entirety, its excellent American Crime Story miniseries dramatization, The People v. O.J. Simpson, featuring what almost has to be an Emmy-nominated performance by Sarah Paulson as Simpson prosecutor Marcia Clark. This drama repeat continues through prime time – but by then, it’ll have some very familiar new competition.
