Question answer and summary

Rating: 10/10 (21 December 2004)

To answer your question, he appears as that because a true patronus takes the shape of something that truly protects you. That is the animal that Harry's dad transformed into (all 4 of the friends were animagus) Overall, i thoroughly enjoyed this movie, and liked the new director much better than the other one, though he was good too.
As to other plot holes, most of it is things they left out from the book that they don't show happening but also don't show NOT happening. That tends to happen often in book-to-movie films. I think they did a superb job at not making it to long with tedious facts from the book and not leaving enough out to go too far out from the book.
