People who live in large metropolitan areas, which cities/towns in your region have a bad reputation or considered less desirable?

Hey everyone!

People who live in large metropolitan areas (over 1 million residents in main city + suburbs), which cities/towns in your region have a bad reputation or considered less desirable?

Of course we are generalizing here, as what is nice is often a matter of personal preference, as some people might like the peace and quiet of a suburb, while some might like the fast paced city life. But in general which suburb is often looked upon with disdain or negativity?

For example, I live in the Metro Vancouver Canada area. The city of North Vancouver is often considered nice and desirable, while Surrey is considered undesirable (sometimes even mocked). But still there are many exceptions to this as some might like Surrey for its multiculturalism or lower housing costs or whatever. So yes, I know its a generalization, but I am curious to hear about your experiences and insights regarding cities or towns in your region that might have a less than stellar reputation.
