This movie is worth your time and money. It had no slow parts. They stayed true to the novel for the most part. The special effects were extraordinary! I would not recommend it for children under 14 though because the scary parts might create nightmares and lost sleep. It would be very intense in I-Max also. I will most likely be seeing it again in the theater because there were subtle background hints that I wish to pick up and think about in preparation for the final movie.
This was a good representation of the book, but left out vital parts such as the battle leading to Dumbledore's death and his funeral. I recommend it because it brings our beloved characters into their dating years and sets the stage beautifully for the final quest!
