I believe I have passed comment on the literary titan that is Dan Brown before. Sure, the plots are nonsensical, the writing awkward, the characters implausible, but he does pull off a good, pacey yarn that evidently gets people reading. I can't begrudge that, I like to see people reading (providing it's not a really old man reading 50 Shades of Blah in 72 pt type on his Kindle in the airplane seat next to me, I don't want to spend the next eight hours in close contact with a geriatric perv, ta). It's easy to take cheap shots, but it's like the kind of people who chase you down the street telling you they don't have a TV you know, that they only listen to Radio 4, and oh hasn't it dumbed down lately. Yeah, yeah, I understand, you're one of the smart kids, no need to go on about it.
To be honest though, he always needed an editor to pare down the awful style and correct the rather obvious errors. Preferably with a chainsaw. Someone ought to tell him to stop trying and keep it lean. Verbs and nouns, I believe, would be safe territory. Someone should sneak any and all adjectives out of the room when he's not looking, for their own good. A kind of descriptive underground railway. Free them from the tyranny. There's no need to describe everything in clunking detail.
Mind you, I write about vampires, robots, and all those dead people you buried in the woods and thought no one knew about. I'm not expecting my Man Booker any time soon.
