MWM,
It is kind of dark but my DDs (9 and 7, DD7 finished before she was 7 and her birthday cake was of course HP theme) enjoyed them. They did not read it initially. I had all the books lying around in the house and after 2 weeks without having another new book, they tried a few chapters and got hooked. I let them watched DVDs only after reading the books (they like the books better) and they did not think the skulls talking on the bus or anything else is scary.
They are celebrating HP week by watching all DVDs again and rereading HP books for the 3rd time.
