These days with the advent of simuldubs, actors not only need to get it right on the fewest takes possible, but they have to do it IN A WEEK, or even weeks before the episode is released in Japan, instead of a few months like they used to. I am honestly surprised they're all able to get the quality this level already. Ex. Chris Niosi took EIGHT HOURS to record the FIRST episode of Mob Psycho 100 as Reigen just because of the sheer amount of lines he has (though Chris isn't as experienced with the craft as most others).
