The first one was standing up for the weak. There was a scene where the children are gathered for their broom flying lesson (if there are any here who believe that an average, intelligent, well raised, child is going to believe that brooms can fly, please raise your hand so that we can get you some help), and a bully in the bunch picks on one of the meeker children. The Harry Potter character leaps to his defense and defeats the bully, to my mind demonstrating both the qualities of compassion for one's fellow man and personal courage.
There is another scene in the movie where the Harry Potter character and one of his male cohorts rescue their female companion from a rather large troll (aka evil). One again the characteristics of courage and caring for the welfare of others is demonstrated. Aren't these qualities we would want our children to have? Wouldn't these be considered Christian qualities? They were taught to me as such.
The qualities of teamwork, personal courage, sacrificing for the good of others are demonstrated in a scene where the Harry Potter character and his two friends have to work through the larger than life chess game.
Finally, the most important scene to me was the finale where he faces the evil antagonist in the movie. The Harry Potter character destroys the evil with 'magic' which at first glance your led to believe comes from the Sorceror's stone, his touch causes the evil character to turn to dust. Shortly thereafter, we learn that the power to turn the evil critter to dust comes not from some 'magical rock' but from (as he is told by his mentor) his dead parents' love for him, specifically, the love of his mother! And by the same token, his love for them. Well, this is certainly a quality we would want children to have .... isn't it?
I found the movie to be clever and very nicely done. There is also a scene in there where the young girl chides her two male companions, asking them "don't you ever read?". The rest of it, the 'magic stuff', is simply entertaining FANTASY! I'm not worried about children mistaking the fantasy for reality and trying to cast spells or fly a broom. Most children (95%+) can discern fantasy from reality, what worries me is the adults who believe this film is going to cause their children to worship Satan, join a Wiccan group, or whatever other rubbish. I worry about the adults because they don't seem to have the same ability as their children to discern what is reality and what is fantasy.
If you want to read it, fine. But it doesn't need to be in the schools.
