I haven't seen it yet but a friend has who said it was good. Not sure if she read the books or not.

I borrowed the first book from the library and couldnt wait for the second to be returned so went and bought it and in a space of less than a week to finish both first and second books, the third book had 3 reserves at the library (there are 3 copies!) and all the local stores are sold out! Wah!!
