You could see this coming. The third season of Big Mouth just arrived, and Netflix has enjoyed the series' success enough to sign a multi-year deal with the show's animation studio. The streaming giant is convinced it has a cartoon powerhouse on its hands, and it doesn't want to squander the opportunity. To some extent, it doesn't have a choice. Netflix's marquee animated series Bojack Horseman is winding down -- shows like Disenchantment can help fill that void, but it may have to experiment with shows like Big Mouth and Human Resources if it hopes to repeat Bojack's success.
