I went to a free screening of Mixed Nuts in college. I was one of many people who walked out, and I think Steve Martin himself wouldn’t blame me.
I saw Brokeback Mountain when it first came out, and during the first homosexual scene I saw several angry boyfriends dragging their dates out of the theater. I feel like every one of them had a ball cap on.
We didn’t walk out of Ultraviolet, but when we left, the whole theater staff was there to see our reaction to how bad it was. They told me I owed my date dinner.
Who goes into Brokeback Mountain not knowing it's a gay thing. That was HEAVILY advertised (and due to the culture of America at the time, mocked as well)
