I really did enjoy Die Hard. It was a great action movie with many things that blew up in improbable ways. I did end up caring more about the villian than I was meant to (but he's Seth Bullock! I love Seth Bullock!) but it didn't make the movie any less kickass. I was shocked with the sort of cavalier attitude that was adopted toward women in the movie though.
( Spoilery explanation under here. ) I guess I should have expected things like that but still.
Also I think Bruce Willis really likes the word "Jerkoff."
