Bad book=bad movie?

The Devil Wears Prada... well, aside from being a statement of utter taste on part of the Devil, it is also the name of a chick lit book I did not enjoy enough to finish--though, I did make it 3/4 of the way through before I said enough. Now, they are making this into a movie. The premise is that an entry-level girl in publishing gets an assistantship at a fashion magazine and her boss makes her miserable and she has man trouble and the rest is formula history.

Spare me.
