I love the show but.....
People who spend years of their lives being drug addicts, alcoholics, strippers, criminals, bad parents, etc. don't look, act or speak the way the characters on the show do! Sorry, but USUALLY the people who live those types of lives are not educated and it's obvious when they open their mouths! Just watch any "reality" show or panel show like Maury Povich or Jerry Springer.
The women on the show have these intellectual conversations with witty banter which is great for the show, but doesn't reflect "real life" at all. Roseanne did it right. They looked, dressed, lived and spoke like a typical lower/middle class mid western family. This show, while it is entertaining, the characters don't fit in with what they're supposed to BE. I know, some people once they get off drugs and alcohol do improve their lives, but this is a far stretch.
