Magic Mike was not a blockbuster. It was not designed to be reflective of the larger culture. $167M is a mediocre (though acceptable) total gross in the Blockbuster field.
Magic Mike is an indie film, reflective of the desires of a small minority. Not the minority who watch male strippers, but the minority who heard that Steven Soderbergh was attached to the project and were immediately sold. These are the type of people who watched Scott Pilgrim, (500) Days of Summer, and The Disaster Artist in theaters. These are the type of people who cry out against a Memento remake and who care about the difference between Room and The Room. These are mostly the people who weren’t influenced by the fact that there are shirtless men in the movie; they were influenced by the fact that they would see craft and cinematic novelty.
