More Friendly Criticism

Like ME2, I am annoyed with the characters on Friends. I think I've mentioned before (but am too lazy to link now) that there has been little growth overall for most of the characters. They have become caricatures instead of people:

Ross was sweet and endearing--now he's just obnoxious and annoying
Joey has just become dumber.
Monica has become more selfish and self-centered.
Rachel has become more vain and self-involved.

Only two characters seem like real people to me:
Chandler has sort of grown--he seems calmer and at peace with where he is in life. Phoebe is not as wacky as she once was. Maybe I'm biased though. Phoebe and Chandler have always been my favorite characters on the show.
