Dolly Well’s ‘Good Posture’  starts with Lilan, a young woman played by Grace Van Patten fighting with her boyfriend. He says she is lazy, and entitled, and do not care about anyone but herself.  Well, we find out he is right, and I kick myself for spending ninety or so minutes with this character. I really disliked this movie about a brat who thinks she can get away with anything just because. The only interesting character for me int he film is played by Emily Mortimer. She plays Julie, a famous author who is acerbic and mean to Lillian. Too bad she is on for just three scenes.
