another surprise is no "Harry Potter movies."
I don't think your average pirate is a Harry Potter fan.
I've seen all of those. I'm surprised classic movies like Shawshank Redemption or Godfather aren't on that. Also, I expected Matrix, LOTR, Titanic (I know blech - but it was really popular amongst people)
Movies are most in demand when they are first released (obviously). Hence why everyone on the list is fairly new. Most people aren't going to download a movie from 1994 because they probably already have it on DVD, or even if they don't, the downloads of that movie aren't going to be nearly as high as a movie just released.
