Well, only Steve really changed. The others were untouched.

Of course it's just my opinion, but I really found the characters as caricatures. The chief was a strong male with a tragic history, Will's mother was a poor, loving mother, Eleven was the child-with-powers experiment, the teacher was the socially awkward nerd, and so on. I'm saying these are caricatures because we got nothing from the characters apart from their main character trait. That's pretty much the definition of a caricature.

The only two characters who were complex were Nancy and Steve. Nancy because she had this internal conflict and Steve because his love for Nancy changed him. They cannot be summarized by a one-line trait and thus are the only characters with complex personalities.
