I thoroughly enjoyed the movie-enjoyed the laughs and the surprises. However, the fact that HP was freely roaming London on the Tube in the beginning was preposterous-especially with the Death Eaters hunting for him so much and actually invading much of the "muggle" world.
There were other times when Hollywood avoided the book and opted for a sensational shot-like the Burrow burning.
My warning to parents is that this movie should NOT be PG. I do not know how they acquired that rating. Ice Age is PG-dead bodies floating around and jumping on Harry's back is NOT. Luckily I read the book and knew what would be in the movie.
