What do you think of the HP books?

So my grandfather gave me the Harry Potter and the philosopher’s stone book. I don’t know which number it is but yeah.
I always started reading it but I never understood what was happening. So yesterday I made time and started all the way from the beginning to read, I think it’s kinda interesting but I don’t get how people always go to wait in lines and stuff for the books. I don’t think they are even that interesting….
