Nashville 10 p.m., Channel 5
No, sorry, the Wednesday episode is yet another repeat. Nice way to lose momentum, ABC. It’s too bad the networks are so locked into the 22-or-so episode season from September to May; it leaves a lot of gaps along the way. Just when “Nashville” seems to be building up steam, it disappears for a few weeks. In this repeat, Juliette (Hayden Panettiere, above) throws a surprise party for Deacon. I don’t quite understand why show creator Callie Khouri brought in Gunnar’s brother, by the way, then killed him off so quickly — before he could fall in love with Scarlett. Subplotus interruptus.
The World According to Dick Cheney 6:30 p.m., Showtime
HBO has a strong documentary component, and now Showtime is ramping up its documentary end. That’s great news, and the cable channel has already had a hit with its two-parter about the Eagles. But “The World According to Dick Cheney,” from R.J. Cutler, is a big fat miss. After hours being interviewed, George W. Bush’s vice president has only curt denials and tired rationales. “If you want to be loved, go be a movie star,” he says in one of his typical lines. He has nothing of substance to say about WMDs and torture, and Cutler and his team don’t bother to press the issues.
