I've been kind of dissatisfied with the Harry Potter film series as a whole; because I was a big fan of the books and the films really didn't match to them in my opinion.
That said, I saw Half-Blood Prince about a year after it was released and was really surprised at how much the films had changed. I watched Deathly Hallows Part I a few weeks ago, and yet again I was just so surprised; but instead of thinking it's quite quite good like I thought of Half-Blood Prince, I thought this one was great. The scene at the beginning where they escape from Privet Drive just blew me away, and from that point onwards there wasn't a single boring moment for me.
I'm definitely seeing Part II at the cinema with my brother (he loves Harry Potter). In the past two years only two films have interested me enough for me to want to see them at the cinema; Black Swan (which I couldn't see because my friend sucks) and now this. I have really high expectations, but I'm sure they'll deliver so I'm really excited!
