You do have some good points there. I think that Harry Potter would be the best if they include all the events that happen in the book instead of picking the main events.

Also I think that it would nice if they could also put some of the events that happen in the video games. (e.g.) POA. The trio has to go and same Neville from a goul. Now in the video Ron is the one who actually same him not Harry.

But who knows. I do know that it does cost a lot of money $$$$ to make the films. But i think that they can manage. Maybe they will do a little better in the upcoming films and will add more details.
