Cartoons are not just meant for kids and after over a year’s worth of so many people spending extra time at home, a lot of folks may have fallen back on animated content once they had run out of other thingsstreaminghad to offer. Whether one’s new to animation or just a seasoned fan, 2021 was filled with spectacular animated productions on television.
Of course, grouping all animated shows and movies into a single group is a disservice to a craft that is much more than just another genre, but instead, just likeanime, more of an artistic vehicle used to develop concepts and stories that could be ridiculously expensive or just feel off in live action form. 2021 has definitely been a fantastic year for Netflix, Disney Plus, Adult Swim, Hulu, and Amazon Prime, so let’s take a look at some of the best each has to offer.
