best: The Sandman by E.T.A. Hoffmann and Fahrenheit 451 by Ray Bradbury
worst: Faust by Goethe and The Dykemaster by Theodor Storm
I literally wasn´t able to understand anything while reading Faust and The Dykemaster. It just wasn´t possible for me. I had no idea what was going on and it was absolute hell. Tbh I still hate my "best" books but at least I could understand what was actually going on and was able to at least work with it so these are the ones I hate the least.
