Motive 10 p.m., ABC
This Canadian import is not a whodunit but a whydunit. In each episode the killer and the victim are identified to the audience at the outset and then the stories jump around in time as viewers watch Detectives Angie Flynn (Kristin Lehman, late of “The Killing”) and Oscar Vega (Louis Ferreira, “Breaking Bad”) piece it all together. It could be intriguing, it could be a headache, but we’re always excited whenever character actor Roger Cross (“24,” “Fringe”) pops up on our screens to suss out bad guys. Pictured: Lehman and Ferreira.
Rules of Engagement 8:30 p.m., CBS
After seven seasons and seemingly as many timeslots, CBS finally pulled the plug on this utility player. It was the kind of sitcom you inevitably end up seeing a few episodes of when you’re too lazy to change the channel. Although by some network standards the show’s ratings would be welcome, when you’re number one you have more options. The series, which starred Patrick Warburton and Megyn Price as long-suffering marrieds, Oliver Hudson and Bianca Kajlich as soon-to-be-suffering marrieds, and David Spade as their insufferable bachelor buddy, joins predecessors like “Still Standing” and “Becker,” which also managed to make not much of an impact but to last many seasons.
