I'm not entirely sure who this was intended for. I believe that I'm the precise demographic that was raised on the comedy of Steve Martin (ever since 'The Jerk') and Martin Short (going all the way back to 'SCTV'), but I feel like the jokes in this special were written for an age group twenty or thirty years older.
Early-childhood photo slide-shows? Seriously? This is 99% 'grandmother humour', mostly safe and unobjectionable fluff, with enough pokes at Trump to seem current, and enough of Short tiptoeing over the line to seem edgy. But apart from the pair's amassed goodwill and charm, it's just flat, stale, and disappointing. The passive-aggressive sniping between the hosts starts off cute but quickly gets old.
I find Steve's banjo infatuation kind of fun — especially his recent collaborations with Edie Brickell (
