Twice, I tried to get through the first Harry Potter movie, and twice I failed. It just seemed lame to me.
I do like the books though. My kids were obsessed with those books and of course I had to read them too in order to see what the fuss was about. I grew up with Tolkien and so those books were along the same lines - except written at more of a child's level.
That said, I'm not a fan of Peter Jackson's films of LOTR and Hobbit either. In fairness, it is a very difficult task converting fantasy fiction to the big screen. It's always better to go to the books.
I recommend you read the original book from which the movie was made. I think you will like it better. Rowling uses Christianity, perhaps inadvertently, as her model for the values of the good witches and wizards in the story. My daughter, born in 1988, pointed that out to me when she read “Harry Potter and the Sorcerer’s Stone.” I then read it myself and had to agree with her. The entire story line is about good versus evil.
