Do you find pacing very slow in older movies?
I was watching Die Hard and felt like there should have been a script doctor who should have taken a red pen and put lines through dialogue and entire scenes. A very slow movie at the start.
Other movies have dialogue for the sake of dialogue. Whereas these days the rule is that if something can be implied, let it be implied. If something can be shown instead of being explained, just show it. Dialogue should be used to propel the story forward, not just kill time.
