I wouldn't go that far. I'd say he's probably still a teenager. That's like berating a toddler for being into Bob the Builder. Salvatore is a decent pulp action writer and it's good that he's keeping young people reading. Hopefully as "I want" grows up, he will keep reading and broaden his horizons.
I think I read all the Salvatore books in college. They were fun.
Did it suddenly get douchebag in here?
Yeah, you're right, they are fun. The action is fun, the bits of humor are fun. Almost every book is tons of fun to read.
Spine of the World was terrible, though. The Wulfgar bits were good, but I can't really be interested in hearing about some some tart's idiotic love problems and engangement to an airheaded prince. Also, Drizzt's section intros should be shot and killed.
I have nothing against reading Salvatore per se (they're good at providing some brainless entertainment, though there's better such), but considering him as your favourite author must mean you're either young, have poor taste and/or haven't read much
