Liberal arts

You don’t have to be a die-hard liberal to appreciate the excellent writing and passionate delivery of “New Rules,” which comes at the end of every episode of “Real Time With Bill Maher” (9 p.m. Friday, HBO). The commentary is often so hilarious that even ultra-conservative guests can be caught giggling.

Come to Poppy

“Unforgettable” (8 p.m. Sunday, WCCO, Ch. 4), the crime drama that was “uncanceled,” returns after a long hiatus with the photogenic mind of Carrie Wells (Poppy Montgomery) still intact. In this reincarnation, the former detective moves to New York City, where she tragically can’t shake the memories of every bad hot dog she’s ever bought from a street vendor.

Ready to rumble

“Total Divas” (9 p.m. Sunday, E!) lowers the mike on WWE’s female fighters as they try to prepare for Wrestlemania while still trying to maintain a grip on friendships and romantic interludes. This is the moment when I usually poke fun at these trashy relationship shows, but considering the subjects’ occupations, I will take a pass.

Sharkey’s machine

You’ve made merciless fun of “Sharknado” (8 p.m. Saturday, Syfy), but did you actually see it? Chances are you didn’t, which is why cable’s No. 1 tweeted show is getting repeated this weekend, the gift at the end of a movie marathon that includes such classics as “Shaktopus,” “Two-Headed Shark Attack” and “Swamp Shark.”
