I read Buddenbrooks many years ago, and liked it a lot, but that's it. Several times I've tried to read Confessions of Felix Krull, Confidence Man, but I bog down pretty rapidly, because I can't stand Krull, and since he's the narrator, you're inside his head (or maybe not, given what he's like, you're seeing what he wants you to).
I was hoping that last word would confuse people, but it didn't slow you down.
