The "random" backflips
I see people talk about this a lot. Near the beginning of the film when Mitch and Abby are visiting Memphis, Mitch does backflips with some kid. I've seen people say it's completely random and pointless. I disagree. It's to show that Mitch is athletic. It makes the chase and some of the stunts he pulls at the end of the film more believable.
People have too much time on their hands.
