Casting of Cage
He's always fun to watch but something seems off when Cage does 'normal', he seems phoney in the domestic scenes and his constant expression of revulsion at the porn-world he descends into seems forced. Cage is a mad bastard and I wouldn't be surprised if he's misused a gerbil here or a power tool there, so it's not surprising that playing a prudish family man who can't stomach hard porn feels like a stretch.
Oddly, he has played characters who are stoic and emote more credibly (like Cameron Poe in Con Air), perhaps if he dialled his performance back here it would feel more real, and contrast better with his crazier scenes later in
