Remember when movies and TV shows billed as “sleazy” actually lived up to sleaze’s promise? No one else does, either, which at least makes the faux-sordid veneer splashed across Harriet Warner’s “Tell Me Your Secrets” less disappointing: If nothing that aspires to sleaziness manages to get there, then we can forgive one show for half-assing an attempt at dirtbag storytelling. Failure is failure, though, and “Tell Me Your Secrets,” its scattered better merits aside, makes a mess of itself by opting away from grime and leaning hard on a tangle of interwoven plot threads written to emphasize the series’ title. The protagonists have secrets, but hoo boy, they’re not the only ones!
