For movies, I have a certain qualification. It has to be a bona fide hit when it wasn’t in theaters, so it can’t be something that hit while it was in Blockbuster, cable or Netflix.
And it had to have a cable/rental/Netflix presence that faded and eventually replaced by a better version of that film.
And the film that comes to my mind is Porkys.
I remember my dad and uncles constantly quoting that movie. That’s the height of my knowledge of that movie. But I do know that it was a massive hit and had a good presence on cable TV.
And this is when my second qualification comes in. It got replaced as the definitive high school comedy by American Pie. Which is sorta ironic because as time goes by, American Pie has been replaced by Superbad.
