My buddy insisted we watch 'The Garbage Pail Kids Movie' and then got weirdly defensive about the plot.
He spent the whole runtime in my living room trying to explain the 'deep lore' of the Stinky Rich character, claiming it was a critique of 80s consumerism.
Maybe it's just me but I had a buddy who did that with the movie "The Room" - tried to explain how it was a genius commentary on betrayal and friendship. What worked was just nodding along and then changing the subject to pizza toppings halfway through. He eventually dropped it when he realized no one was taking the bait.
