Well, despite the bad beginning, this turned out to be an extremely interesting thread.
One of the things i like most of GG is how they laugh at stereotypes. In my opinion, the characters are at the edge of stereotypes: Lorelai is the coolest mum, Ms. Kim is the most protective mum (she is Korean, but could have been Catholic, Protestant, or even Jew!!)., Jess isn't a bad boy, he is the worst!, Emily and Richard are really snob and the Huntzberger (is it well spelled?) are the worst rich people ever. and Taylor!!! He is the most... well the most Taylor! And Stars Hollow is the better place to live!!! I think that is nice about the show.
I particularly "enjoy" Emily's maids: it shows, in a funny-pathetic way, the situation of thousands of immigrants from Latin America or Eastern Europe, the way they are treated by Emily really sucks. And only one of them made Emily be called to court! She doesn't even know where they are from ("what language is that" when Rory is speaking in Spanish, she didn't like to hear that conversation and she fired the maid!!!!!).
So, although the show is not particularly "politically correct" there are this things that make this TV show so special
