Well despite the terrible writing and characters being as deep as a piece of paper I quite liked the idea of the vampires in Twilight each having their own unique ability. It was also interesting the way she actually acknowledged the fact that having such strength would be quite difficult to not use unintentionally, as seen by Edward putting a dent in a car just by putting his hand out to stop it.
I don't like the Harry Potter films (mainly because I am a huge fan of the books), but I think the tone of the films was overall done very well. There was the occasional typical "humour" that felt out of place, but seems to be necessary for movies, but otherwise it felt dark when it was supposed to be.
They also made some superb casting choices. A lot of the characters look nothing like they do in my head, but Alan Rickman as Snape was a perfect choice, he nailed the role completely.
