Again, why are you asking me about ‘Stephen King films’? I’ve not even mentioned King, and I don’t much like his books. It’s really odd that you’re fixating on this.
It’s peculiar for anyone who supposedly teaches an arts/humanities subject to attempt to win an argument by disputing points that your opponent wasn’t making in the first place. I hope that isn’t how you teach your students to analyse and critique, because that’s really not how it works, and you’re setting them up for academic failure.
There is no such thing as ‘a Stephen King film’. He is not a filmmaker. Carrie (for example) is not a ‘Stephen King film’. It is a Brian De Palma film, with a screenplay adapted by Lawrence D Cohen from a Stephen King novel.
Either way, I don’t care about your views on Stephen King and I don’t really care what you think of any film adaptation of his work. I make no claims one way or the other for any films based on his novels to be ‘great art’. I think the term ‘great’ is pretty meaningless in the context of art, in fact.
I do take issue with you dismissing an entire genre of cinema as devoid of merit while purporting to be a teacher of film, and with your inability to recognise that your personal dislike of a genre does not mean it cannot have any artistic value.
I’m certainly grateful that the people who taught film and literature at my own universities didn’t teach like you.
