Are you a fan of Harry Potter?
Yes very much so, he's my all time favourite wizard.
Do you prefer the books or movies?
I prefer the book because I can picture the characters for myself, in the movies it's somehow forced into me. What about you?
Same here. The books can also go into more depth, while the movies get edited for time.
I agree. Which Harry Potter book do you like the most out of the seven? 
Prisoner of Azkaban. I thought it was such a great story. I must admit, I did not expect the twist with Wormtail's reveal.
Oh I love Prisoner of Azkaban, I love that it's somewhat darker than the other books. Also the Wormtail reveal, haha, I agree.
Did you read the books before seeing the movies. I didn't start reading them until after I'd watched the third movie.
I watched two movies before the book. Once I started reading the books I was hooked, I made sure to read the books first.
