I really don't like it. I'd definitely call it bad, but it's probably not fair to say that it's objectively bad.

I think the general attitude is more casual or less caring about details and presentation and things like that than I am, or what I'm used to back home. Stuff like how people dress at weddings, or whether you directly introduce two people you know who don't know each other. Or how people in the Midwest make this "Ope" noise as a kind of replacement for "excuse me."

It's mostly small stuff, but there's enough of them that they add up. The city and metro isn't as nearly as bad with it. People tend to care more for lack of a better phrase (although they have their own minor issues -- constant little brother syndrome with NYC, how they think they invented pepper and egg sandwiches, etc.). But you can still feel it around the edges and I'm tired of it.
