Nice to see this thread get bumped up, just because i love this movie so much. It's nearly impossible to not see this movie through a 2017 lens if you haven't seen it before, so i can understand if it doesn't hold up to some.
and two things - possibly mentioned in the commentary, i can't remember, it's been a while since i listened.
one thing that always bothered me was the Die Hard 2 doesn't take place during New Years Eve. one of the last lines in the movie is Argyle saying, "If this is Christmas, I gotta see new years!".
The other is the shoot the glass scene. the idea that the german terrorists don't understand "schieß dem Fenster" until Hans says it in english is just nonsense. but you know what? i don't care. i'll go to the mat for this movie....i'd guess along with every other 35-50 year old dude.
