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

I'll preface saying the original Star Wars triolgy is three of my all time favorite films....with the three "prequels" worthy of watching. For some reason, I have not had interest in:

Lord of the Rings
Harry Potter
Twilight series

Just for clarification, all men should watch Saving Private Ryan, Terminator 1 & 2, and the Bourne series. It's just something that must be done.
