Whether by guilty pleasure or genuine appreciation, HBO’s soapy limited series “Big Little Lies” has been one of the most talked-about shows of the spring. And now, after many slow drives along the Bixby Bridge, Motown-adjacent song cues and waves crashing on the Monterey coast, the series is over.All along, David E. Kelley’s drama (based on Liane Moriarty’s 2014 bestseller) promised us a murder, and on Sunday its victim and perpetrator were revealed. Although for all the petulant, privileged behavior on view for seven episodes, it’s hard not to relate to one of voices from the series’ long, flashed-forward investigation: “One dead? We definitely got off light.”Here are six highlights (so, obviously, spoiler alert):1. The monster is slain: Though statistically speaking all odds pointed to Nicole Kidman’s Celeste as the finale’s victim, Alexander Skarsgård’s abusive “monster” Perry met a just end Sunday night. After Perry learned of Celeste’s beachfront apartment and plans to leave him, he confronted her again at Trivia Night, which led to a violent scuffle between the two of them along with Jane (Shailene Woodley) and Madeline (Reese Witherspoon). Finally, it was Zoe Kravitz’s Bonnie who stepped in and shoved Perry backward down a flight of concrete stairs and what looked like some pointy rebar — but if you read the book you knew this part.
