I am not a "Potter Head." I've never even glanced at any of the books, nor do I have any desire to. In general, I don't like entertainment appealing to kids...I don't like "Shrek" or "Finding Nemo" or any other thing made by Disney or Pixar. I've heard it all before "but Amanda, there's a subtext that is written for adults to understand," "but Amanda, the story is so great, anyone can enjoy it." "Well," I reply, "Bah Humbug!" I don't care that I seem to be in the minority among many of the people I know, "Bah Humbug, Harry Potter."
This is the third Potter movie I've been dragged to. I think that the 1st one was the best, it told the most interesting part of Potter's saga--the other 2 movies seem like a giant pool of salad dressing drowning Harry's baby greens. The 2nd film was awful. The 3rd one was better than the 2nd, the direction by Alfonso Cuarón was good, as was the acting, but I feel that the film lacks a lot of substance unless you have read the book. What's the difference between a moggle and a dumbledorf? I don't know, I don't care either.
You'll like the movie if you already like Potter, but I'm still searching for something to warm the cockles of my heart.
