The movie had that "animated series" vibe from the start, makes me wonder if we are returning to the late 80's-90's where most of the big animated movies had their own spinoff series (The Jungle Book - The Jungle Cubs/Tail Spin, The Lion King - Timon and Pumbaa, Aladdin animated series just to name a few). Then saying that, getting a spin off has always been a thing for the larger successful movies, not always turned into an animated series but to poop out one or two straight to VHS/DVD/TV movies.
If they can make money on it, they'll milk it for all its worth. Lets hope the series doesn't taint the movie.
