It is understandable to be sad about having to wait longer to get the full picture of season 2 of “Invincible.” But once you see all four episodes of this first part of the season, it becomes clear that it is worth the wait.
For one, the new episodes look stunning. The studio Wind Sun Sky Entertainment, as well as animators Maven Image Platform, have vastly improved the animation from the first season, which looked stiff and had limited animation, often over-relying on CGI. By comparison, the new season has more fluid action scenes, with proper choreography and a sharper art style to match other action-heavy animated shows.
As the story heads into outer space and involves dozens more characters, as well as the threat of an invasion by a huge alien empire, the production is bound to get bigger. This means more work for the animators, and more time to produce the show. At a time when poor working conditions in the animation industry are becoming widely known, that “Invincible” is seemingly taking longer while avoiding crunch time is not a bad thing.
While we’ll only get half of the season this year, remember that we did get an extra episode in the summer about Atom Eve (Gillian Jacobs voices the teen/adult Atom Eve; Jazlyn Ione the pre-teen version). That episode was the same length and quality as the rest of the season, which also takes time.
And that episode length also affected things. Remember that each episode of “Invincible,” unlike most animated shows, is an hour long, as opposed to the standard 22 minutes. That means more work for the animation team, and it also means that we essentially get twice as many episodes, from a certain point of view. Sustaining that level of quality for that runtime is not easy for a production.
