I knew that the first part of the movie had to be a little slow as the plotline of the book starts out without the typical constant, riveting action of the other Harry Potter books. However upon seeing the movie, I felt like the hours flew by and I was engaged the entire time. I loved every minute and it was much more exciting than I expected it to be. If you're not a Harry Potter fan though, it may be a little sluggish. Not for me!
