Steven Soderbergh’s “Magic Mike,” the oiled-up beefcake summer surprise of 2012, was a surprisingly moralistic movie, despite its crotch-pumping dance numbers and its meticulous depiction of the social world of Greater Tampa-St. Pete male strippers. To be specific, it was the fairytale about the princess who kisses a frog – a frog with an unbelievable six-pack, wearing a fake cop uniform over a leather thong – and restores him to humanity with the power of love.
