What novel could you not finish?

I could never make it through The Fellowship of the Ring (the first volume of Tolkien’s Lord of thr Rings trilogy). I found the story alluring enough but I felt the writing was horrible so I just gave up on it.
What about you? Have you ever given up on a book? If not perhaps you’ve read a classic that you felt was grossly overrated. For me it was Summer of my German Soldier by Bette Greene. And although they arent novels I’d also like to add any play by Shakespeare to the overrated list.
