In the very first film, a teenager has sex with an apple pie. Another drinks beer that contains his friend's semen. Another has sex with a high school classmate's mother.
Unless you mean "adult film" as in pornographic film, I think we can come to an agreement on the answer to your question.
You're right Mr. Hankey.
However, After I watched the whole series on our VCD player, American Pie 1, 2, and 3 are great but 4, 5, 6, 7, are a major turnoff. In fact it doesn't look like an American Pie movie but an adult film made it on to the big screen. Especially "The book of love", and it's painful to watch...you will not laugh at all and sometimes It can be offensive like: The girls are running outside naked.
