Can't they have put more budget into the continuation to a fan-favourite series? Animation's wonky, like everything in the hidden world is just 3d shapes that are completely flat.
Character designs are kinda unsettling (should've stuck to the old animation and designing).
Quite a number of plot holes and unreasonable events made for the show like they're skipping steps.
The thing that maintained however, is great quality music and sound design. This is all just from watching the first few episodes. This is too marketed for kids and the conversations are too fast and cringe like any other show these days.
