For me, it's Harry Potter.
I know it's one of the most popular film franchises ever and people rave about how fantastic the books and the movies are, but I'm just not interested.
There's just something about the magic and flying brooms that just doesn't appeal to me....
I think part of it is the first book came out when I was in high school so I wasn't interested in reading it then and then all the movies were released when I was a young adult and I was definitely not into "kid" movies at that stage of life.
I have two young kids now who may come to me one day and want to read the books or watch the movies and if they ask me then I might finally give in and see what all the fuss is about.
Until then though, I'm holding out and will remain naive to Harry Potter.
What about you? What movie have you never seen before that everyone else on the planet has?
