I'll share something about watching T2: in my experience, it was a different movie if you saw it after the first week, than if you saw it right away (similar to Jurassic Park in that aspect). In the opening night theater, people were chilled at the machine's lack of human feeling, etc. The violence was not part of a punchline - it was part of the story-arc.
When I saw it again, a month later, the audience had completely changed - they WERE laughing and cheering at times, and rather inapproprate times, at that. It had become a Summer Movie (TM).
