I think there's even more disdain for Shawshank. It's considered a middle America favorite. Art film for people who frequent malls. A middling film for people with mediocre tastes, I believe the esteemed Devin Faraci said this.
The thing is Shawshank is far more beloved, rated more highly, so it's criticised in this context, for being over rated since it's probably one of Americas favorite movies. Everyone has seen it because it was shown on cable constantly, lots of young people saw it and thought it was deeply profound.
I like the movie, personally. Not a favorite or anything, but it's effective and satisfying.
