Classic/Popular movies you've never seen...

This thread is very interesting because Ive seen most if not all of these movies.
So, I must ask to those of you that haven't seen Lord of the Rings, Godfather, Harry Potter, Lethal Weapon, Star Wars, etc.

Is it because you folks aren't that into movies?
Or is it just a lack of interest in the stories/films themselves?

I can understand no interest in a movie like The Pest starring John Leguizamo but a lot of these flicks are either classics or just entertaining. I read the Lord of the Rings and had created visuals in my head but it was even better to see the characters and settings brought to life.
