no it doesn't. you're probably uncomfortable watching it because you're used to cliff and jasons presence, and i get that.
however super fans and old schoolers that weren't frightened by their progression are going to feel differently. Rob was the best choice hands down. so cal dude, has plenty of credibility before, chops of steel, endless energy, gets the crowd engaged, seasoned touring vet, etc. no one "known" would fit better imo. a "nobody" or some you tuber would never work for a band at this level. Not only are you metallicas bass player, but you're 25% face of a major BRAND. you have to act accordingly. They're an entity on the level of a major sports team. you can be in some band like Testament or Death Angel and fuck up (i.e be addicted, be wasted at a gig, write a shitty social media post, etc) and a few thousand people MIGHT care... in METALLICA its a bigger news and can effect a lot of money.
who would fit the bill better?
