Those university choices look cool I'm thinking of applying to St George's, Kings, Barts and UCL, do depending on GCSEs, UKCAT and AS - mine are probably going to change a lot though
Prisoner of Azkaban is definitely the worst. Plus, the Dementors scare me a bit.
I think Prisoner of Askaban is brilliant! The worst in my eyes is either Deathly Hallows Part 1 or, you're probably not going to like this, Goblet of Fire. I just think that Goblet of Fire is too light-hearted and it get rids of the scene where we were supposed to have Dobby too. That being said, the scene where Voldemort is reborn is epic.
