I'm a HUGE fan of the Harry Potter movies! I only just started reading the final book within the last few weeks and it's SO good... I can't wait to see the first of the last two movies in November!
Now I know a lot of "good" Christians don't watch the movies or read the books & think it's all demonic but it's no more demonic than most of the music kids listen to nowadays or the other movies they watch that promote violence & crime! If someone ever took the time to watch, you would see that it's the classic good versus evil theme that we all struggle with daily. God is acknowledged in the books/movies & so is Jesus (Christmas is celebrated in just about every movie). And besides that, the Bible says that God will get the glory in EVERYTHING & for those of us who love Him, all things work for our good, according to His plan (Ephesians 3:20, Romans 8:28)! That's not the point of this post but I just thought I'd preface with that for those who, without reading further, will quickly judge... anyway, the fight between Harry Potter & the "good guys" from the series is against Voldemort, an evil wizard who is determined to rule the world basically. He uses all these evil beings - dementors, death eaters, etc. - to do his bidding. They kill for him, possess people & intimidate them into doing what they want.
