As far as the acting, this is the best of the movies, very emotional and you could feel the tension. However, it seemed to drag a bit at times, and I was looking for more of the scenes with Kreecher and those at Malfoy Manor, and with the Dursleys. If you have not read the books it will be hard to follow. I know that this is only a part one, but I have to say, I was hoping for a little more. Or maybe better choices of what scenes to keep, which needed more, and which they could just gloss over.
This is not your father's 3D movie. We decided to see the full IMAX 3D version. There were 3 of us, all sci-fi lovers and all 50 years old. We all loved the movie, even though it seemed very much like a common story - think Matrix meets Ewoks. The color and quality are amazing, and even though 2 of us wear glasses, the 3D glasses fit well and comfortably over them. About halfway through the movie you forget it is in 3D - no gratuitous 3D effects! We plan to go back and see this film in the regular 3D and the non 3D versions. I was skeptical - but this movie is a treat! Get there early though - we had to split up as the ticket machine was not working and we had to stand in line anyway.
