>>2912430around the release of dog days season 2 the writing got substantially worse, and the main author much more frequently fell into the trap of not having enough stakes, of having everything be happy and safe for the most part.
the main series manga continuation (force) was made by a trash mangaka who made a trash manga and pissed off literally everyone so hard it got definitely-not-canceled.
the spinoff manga about vivio (vivid) is alright but spotty in quality with entire volumes of nothingburger new cutesy characters, it's the only thing he's made in like 10 years that's had moments as good as the original 3 seasons.
the spinoff manga where everybody is happy and alive (innocent) is alright, it's pretty cute.
the spinoff spinoff (vivid strike) was kinda meh overall but not that bad.
the new movies, except for movie 1st, are a downgrade in every respect except visual fidelity. they're shitty adaptations and they change things that don't need changes, and the direction cinematography-wise is absolutely terrible compared to the originals. the newest movies are just adaptations of the ancient psp games with some extra characters.
tl;dr almost nothing new and substantial has occured for forever
