From school, Cider with Rosie. Snore. And anything by Dickens. Dickens is just a pantomime in print form, or at best a soap opera - Lord knows how he got a good reputation, I'll take "Neighbours" or "Home and Away" any day. In fact, much pre-1900 fiction is unreadable by today's standards (Wilkie Collins, Frankenstein, Dracula, Fenimore Cooper) bcos the construction is dreadful. I guess they didn't have editors back then though.
Robert Heinlein and Wilbur Smith can go in the bin. Fine for adolescents, but when you get older you realise it's all either wish-fulfillment fantasising or political dogma. Tom Clancy stuff has gone that way too, particularly the various spin-off series.
Arthur C Clarke's Rama series is lousy too - Clarke is probably the only writer who could make exploring an alien spaceship boring. Other dulletantes are Colin Dexter (good TV series but the books suck), Kazuo Ishiguro and E M Forster. Terry Brooks started well with a nice rip-off of LotR, but after the second he lost it big-style, so if you've read one then you've read them all.
To sort of bring music into this, any of those books with pictures of painted-and-inlaid guitars. I always look at those and think "yeah, it's pretty, but how does it sound?" The attitude of the painters (and the guys commissioning these things) seems to be style over sound quality, and that's something I've never understood.
