Clearly Kail was trying to find a visual equivalent to the energy that one might experience from seeing it live and it is obviously preferable to simply plunking one or two static cameras in front of the stage for the duration (as anyone who saw the woeful filmed version of the Kevin Kline-Linda Ronstadt revival of “The Pirates of Penzance” can attest) but a little more restraint in this area might have made it a little more effective in the long run.
