Have you seen the CBS-TV show Joan of Arcadia? This has to be the smartest, deepest, and best overall show in a long time. Even the photography is great. Sure, other shows are good. The West Wing is well cast and has some clever writing, CSI: Anywhere (and everywhere, apparently) has some great science behind it, and many other shows have some really fine points. But only Joan puts it all together in a great package. I can't recall another drama that has made me think like this one does. Or feel. Or pray.
And it's very funny for a drama. The plots aren't usually funny, but well-rounded characters and their interpersonal dynamics often lead to humorous dialogue and situations much as happens in real life. Many characters in dramas are too serious while many in comedies aren't serious enough. This show is a great blend that makes the show highly believable and easy to fall into.
