Zoe/Doctor Hart is like the center of an old 33 1/3 RPM record: Vital but not drowning out the surroundings whirling about her. I love "Frasier", but "Frasier" has no such low key "hub" character: "Frasier" is multipolar with 5 main characters. A similar comparison of "Hart of Dixie" might be made with the really grand Spanish soap opera, "Gran Hotel": Another multipolar drama with no orienting central persona. I lived many years in Tennessee, Arkansas, and the Florida panhandle( near Alabama ) and I vouch for these " Bluebell" characterizations & the realistic plot/s, although the Hollywood set is sometimes annoying in its fairly trivial errors, mainly having to do with nature, but also(e.g.) the very unlikely parking meters in this tiny, out-of-the-way town. I have lived, off & on in a similarly small Florida panhandle "Trump" underclass town, so I pick up on little things.
