I read 3 and 3/4 of them. Breaking Dawn got so bad that I just stopped -- something I very rarely do. They're poorly written and filled with craptastic characters.
My real problem, though, was that I read the first book and then moved right on to read Anne Rice's The Vampire Lestat. Good lord. Talk about opposite ends of the spectrum 3nodding It goes without saying, my eyes were opened to the poor writing and characters of Meyer.
Really, I can't say it better than The Ghoul In Pajamas did, so I'll just stop here ^^
By the way, The Ghoul In Pajamas, your words left me in tears of happiness. They were so eloquently written in their simple truth. You have made it to my list of favorite people :'D
