there's a scene where Charley tries to model the kinky boots. He stumbles and falls about the stage like a fool till Lola takes over. I'd find it more interesting if Lola taught him how to walk during the course of their song till Charley gradually realized he was enjoying himself, ala Gypsy's first Strip. Having Charley gradually come to terms with his own kinky side would have been a more interesting arc than the daddy issues he's saddled with.
The pre-Broadway tryout ended with the child Simon and Charley hugging their fathers. Since Simon's father was established as abusive that moment felt creepy and dishonest to me.
