Mary Steenburgen in <em>Parenthood</em> (1989)
Mary Steenburgen is always good, and Parenthood gave us one of her best roles. As Karen Buckman, she's an unflappable mom struggling with her kids, her husband, and what the world expects her to do. She's so... likable. Seriously, doesn't she seem like someone you could hang out and chat with for hours?
