Geoff:
But there are times when things are altered or omitted which then 
create problems for the filmgoer who is not conversant with the 
books.

For example, one omission which has always irritated me is that in 
the POA film, nowhere is it made clear to the non-fan that the 
reason Lupin knows what the Marauder's Map is, and why it could 
be dangerous to Harry in the wrong hands, is the fact that he was 
one of the Marauders and helped to create the thing!

And, returning to HBP, why did Luna find Harry in the train? What 
was wrong with Tonks, as in the book?
