A selective critical checklist of notable weekend TV:

Big Little Lies (Sunday, 9/8c, HBO): Here's the clash of the acting titans we've been waiting for. In the second-season finale of the addictive domestic drama, it's Kidman vs. Streep as Celeste (Nicole Kidman) puts her lawyer's cap back on during her custody hearing, interrogating her calculating mother-in-law Mary Louise (Meryl Streep) about Perry's childhood. What sort of secrets could this tactic expose? And will the Monterey Five be able to keep a lid on the lie they've been sharing about Perry's death?
