Do you think that if the trailer for Avengers 9 ended with Thanos saying "I am inevitable" would be nearly as exciting as the trailer for Star Wars Episode 9 ending with The Emperor's laugh?
I don't think so.
People like showing how old and out of touch they are whenever we have topics discussing the cultural impact of the MCU. Like, they just spend their time twisting themselves into knots about how the biggest cinematic event in history and the climax of the most successful film franchise ever somehow made no impression with audiences and will be forgotten in a few months while their favorite movies/franchises from when they were kids will continue to be hot shit forever.
