You want overrated? Ok... The Sound and the Fury, Middlemarch, Gravity's Rainbow, Tess..., The Tin Drum, Fathers and Sons, The Trial, Call It Sleep,
Missing: Catch 22, Simplicimus Simplicissimus by Grimmelshausen, Studs Lonigan, God Bless You Mr. Rosewater, The Man With the Golden Arm, First Circle, Gulliver's Travels, Heart of Darkness, Naked Lunch, The Mayor of Casterbridge.
I love TSATF, Middlemarch and Tess. The latter is the great English prose tragedy. And how can something as majestic as Middlemarch be overrated. Faulkner and Pynchon are obviously an acquired taste. I think the Turgenev is there because it accurately described the sort of personality who take over Russia over 50 years later.
