Yes, the South is different. But isn't it sad that the song "Sweet Home Alabama," which was written in the first place to object to sweeping generalizations about demon-Southerners (all Southerners being white, of course, in this anti-Southern view) is now gracing a movie that cozies right up to Southern stereotypes? (And for those objecting to the sentiments of the song, perhaps you should learn a little bit more about Lynyrd Skynard and Neil Young, and what that song actually said about their attitudes--and how Young responded. What Skynard meant by the song and how SOME of their audience have interpreted it over the years are two different things, just like Springsteen's "Born in the USA" has been used for political purposes that are the opposite of the song's sentiments.)
For people who think every white Southerner's favorite evening wear is a white sheet with burning cross as accessory, they can gloat over the stupid hicks in this film. For people who want to fantasize that we can still live in Mayberry, they can groove on how pretty it all is. (Mostly.) People see what they expect to see. (Except black folks, who'd better not expect to see black folks living in the Alabama of THIS movie.) Reese Witherspoon herself, a well-bred Episcopalian débutante from Nashville, is a negation of Southern stereotypes, and an example of the Southerners we never see as characters in movies.
Meanwhile the movie itself is so innocuous that it dissolves while you're watching it. I've been sitting through the unending USA Network commercials for their showing of the flick, and getting the impression that the only reason they're showing it is to piggyback on the popularity of Dr. McDreamy.
I suppose there are worse ways to spend an evening. But don't imagine that you're seeing anything to do with the actual South. Or actual human beings.
