They’ll no longer necessarily feel the need to spend as much time perfecting each and every episode detail as if those will be the last ones they’ll ever work on, which will allow all involved to plan for regularly scheduled vacations during the between-season hiatuses.
Justin Roiland credits Adult Swim’s massive renewal order for setting the writers up for a future that doesn’t need to be peppered with delays and premiere date guesswork.
Which can actually be proper hiatuses now, instead of mini-epochs.
If Rick and Morty sticks to ten episodes a season, the show will be around for at least seven more seasons, and that kind of job security can be a boon to one’s creative juices.
