List of Improvements on the Book

[Marcus]

Instead of nitpicking the movie where it changed details of the book, 
here is my preliminary list of where the movie actually improved 
things IMO.

(1) Fluffy's origin.  It always bothered me that somebody from Greece 
shows up in Scotland with a gigantic three-headed dog.  The 
logistical nightmares that entails boggles the mind.  Where was the 
MoM?  It makes more sense for somebody from Ireland to have him.  It 
might even be an Irish bloke living in Scotland.  Yes, yes, I am 
fully aware of Cerebus, or whatever his name was.  But Centaurs 
aren't exactly standard British mythology either.

(2) Norbert's fate.  It makes more sense for Dumbledore to step in 
and take care of Norbert.  I've had a very hard time swallowing the 
idea that Draco Malfoy would sit on such a juicey piece of 
information for more than a week and not try to take advantage of it.

(3) The end of the quest.  It has always bothered me how quickly 
Dumbledore arrives on the scene.  Just how did he get through all the 
obstacles so fast?  If he had a back door, the bad guys could easily 
find it and use it.  If only he could use it, then what use is all 
the obstacles.  Just seal the passages up and be done with it.

As it is, he showed up "in the -- TA DA! -- nick of time."  In the 
movie, Harry collapses and he is found at an unspecified time later.  
This makes far more logical sense.
