The Telegraph has a list of the 25 Best Book to Film Adaptations or "Twenty-five films that made it from the book shelf to the box office with credibility intact."
The full Harry Potter series is on this list. Obviously whoever came up with the list never read the books. I won't go to them anymore they are so far afield from the core direction of the books its not even good enough to be pathetic.
And LOTR was lower on the list than HP. For me, the Telegraph is now a source to be avoided as this list is prattle.
