McMillionsThe story behind the latest documentary project, “McMillion$” (HBO, 10 p.m.), is undoubtedly a fascinating one: That the famous Monopoly game that the huge chain ran from 1989 to 2001 was entirely rigged, with the top $1 million prizes going to one or two families related by blood. Telling the story which grew out of an investigation by the FBI office in Jacksonville, though, the filmmakers take a podcast approach, slowing down the action and throwing in extraneous detail to make what would have been a decent feature length story into a six part, six hour slog, with less a prospect for ultimate satisfaction than the original fast food contest.
