It gets sooo boring! They have sex like 6 times a freaking day! It is too much smut and I never thought there could be such a thing as too much smut. I ended up skipping most of the sex in the last two books so I could hurry up and find out what happens.
I only read the first one, and I still havent forgiven myself for exposing myself to such a travesty. It was even worse than the mess that was Twilight. It was essentially an abusive shopping list (incredibly repetetive. I should have had an 'inner muse' drinking game to help me stomach it) masquerading as BDSM literature in order to titillate and misinform bored housewives.
/end rant.
I also blame that series for the recent assumptions I've heard about women all having a secret need to be submissive *eye roll*
