Martin Amis was worth reading once upon a time, back when he had something to say and an interesting way of saying it. Like the Rolling Stones or I'm Sorry I Haven't A Clue, he has become a pastiche of himself.
I found Bring Up The Bodies an easier read than The Girl With The Dragon Tattoo.
No one should ever need to feel ashamed of their reading choices. I might pass judgment on the quality of a writer's work but that doesn't imply judgment of the person who reads it.
Re No one should etc - fwiw I totally agree, I remember choosing a book on Michael Jackson (ooh years ago -many years ago) for my son when he was quite little, the person serving me in Blackwells sort of sneered implying it wasn't a "proper" reading book, "oh" I said "does it only have pictures then", "no" replied oik, "well" I said "it's a frigging reading book is it not, hopefully spell checked etc so he will absorb and learn", never went back there.
If you enjoy what you read then that is all you need to think about, they said the tinternet would kill books, of course it has everyone can see there are no books anymore
, computers will make you illiterate ? of course they have, have you ever typed a comma into an address bar instead of a full stop, very dodgy, it will not be what you're looking for, all good fun what.
