Bent 9 p.m., Channel 7
NBC doesn’t appear to have much faith in this new comedy, with plans to air it in back-to-back installments during the next three weeks. It’s too bad because, although slight, “Bent’’ definitely has its charms, as a tightly wound single mom (the game Amanda Peet, pictured) and the charismatic slacker contractor she hires to renovate her house (genial Boston native David Walton) do the rom-com shuffle with brisk aplomb. Plus, it brings back to TV a trio of always welcome faces, J.B. Smoove of “Curb Your Enthusiasm,’’ Jeffrey Tambor of “Arrested Development,’’ and Jesse Plemons of “Friday Night Lights.’’
