Am I Missing Something?

Ok, I am kind of confused.  I can only assume that I’m missing something.  I must be.  There were loads of amazing reviews on Amazon (and some very bad ones which turn out to mirror my opinion).  Magazines were raving about it, The Week included.  Now if it was one of those things that is so bad it’s actually good (like The Tudors) then I might be able to understand, but I personally think it’s just bad.  Fifty Shades of Grey is disappointing me.  It’s repetitive, and completely unbelievable.  And I’m not even a third of the way in yet.  I’m not a prude, but this book has me cringing.  The dialogue is ridiculous in my opinion.  Now, I know writing is difficult, given that I’m something of a wannabe writer.  Personally though, and I really don’t mean to be judgemental and stuff (though I know I kind of am being), but if I had written this I’d have been too embarrassed to allow anyone else to read it.  I don’t post on fanfiction forum things.  To be honest I can barely cope with the whole blogging thing and I’m a newbie to forums and stuff.  Anyway, I guess I just want to say, before my Mum told me it was rubbish, I was hoping for more from this book.  Both my Mum and me are thoroughly disappointed, and can only assume we’re missing something.  If someone can explain what, I would be grateful.  But personally I like my books a bit more believable, with characters you can somewhat sympathise with, oh and that aren’t too repetitive.  I guess there’s a reason I don’t read romance novels.  And for the record, I’ve yet to write anything I’m comfortable with anyone else reading.  I know I’m rubbish.  Though maybe I could turn that into my thing?
