Harry Potter and the Goblet of Fire

I saw Harry Potter and the Goblet of Fire yesterday
with Marija, Helena, Phoebe, Agnes, Gary, Anand, and Patricia.
Well, I enjoyed the movie as I enjoyed the other 3 movies.
The 4th movie is more darker. It was rated PG-13 because of
action pack and more darker side of Harry Potter that appeals
to teenagers. I wouldn't ruin the movie for you, so you should
watch it. The only sad part is that one of the cute guy in Harry potter
not KRUM, but the guy from Hogwarts is too cute to die. Opps
that's just a preview. The theater was crowded. We had to wait in line for 3 hours
to see the movie. It was a long line.

What do you think of Harry Potter? I think if I read the book
I will get more detail story of what the series is all about.
The movie only give you general premise of the movie.
Let's see how well the movie will do this weekend.
Will it be number one again?

Why do you think Harry potter appeal to the greater audience?
How does it great a lot of buzz? I want to know this because
I'm a marketer, and I'm all about creating BUZZ.
