As it's a film for thinkers and not a superhero, sci-fi type actioner, it's going to get some kick back.
Glad you enjoyed it.
I don't think peoples issues with the film stem from the superhero/action culture. The movie has a huge amount of issues that stem from the overload of dialogue (which is difficult to hear at times), the abundance of characters with little to no introduction/importance, a lot of us watched this movie with little to no knowledge of Oppenheimer and we were at a massive disadvantage (the movie wasn't friendly for people who weren't aware of Opp and the book it's based on) and a lot of us had no idea what the black and white scenes meant.
