My current favorite show. Blessed by good actors and good writers. The dialogue is well crafted, and there's a nice bit of occasional comedy thrown in to temper the drama. Can't say that it's realistic, but who cares? It's engaging and entertaining. It's hard to put my finger on why I like it so much. Perhaps because it's intelligent and has very good plot lines. Each character is different and believable, and each has his/her issues and demons to deal with.
