Unrealistic
1. How come the parents don't say anything when they are kissing at the end? Surely, they weren't that liberal in the 80s?
2. How are the kids able to cause so much mayhem in the school and the library, including smoking pot, and nobody finds out or there are no implications of consequences the following week? The teacher was not that dumb. But the way they showed him, he had no clue what was going on.
