Gambon's Dumbledore in "The Prisoners of Azkaban' was fine IMO and maybe it's because I like the third one the best; but the character in "The Goblet of Fire" seems to be a bit ... disoriented.

The script might be the problem, considering the fact that too much from the book was taken away which seemed to make the plot scattered. It makes me wonder at this point how the HP franchise is going to handle an even longer 5th book when the next production begins.

One of the "qualification" nowadays to be labelled a bad movie is - too long. Have we been told that we don't possess longer attention span anymore? What is wrong to make a longer movie?
