For someone not astute in movie magic, you probably won't see the plot unfold, so go see it. Special effects ok, acted well, some did better than others.
there are a few moments that may be scary for small kids, but overall very good movie. All the witches were well played, and the characters were believable.
Althought I am not a true HP fan, my kids have grown up with this franchise. This movie was good and followed the overall themes. My daughters have read all the books and are anxiously awaiting the second half....definetely a must see.
overall, the story drags a little and there were a lot of conveniently inserted short takes to explain the plot, but I would recommend this for a date.
