I hate the Blue with translucent Neon Orange going on with the Hero side, the sets feel more low quality because of that (Translucent colours in general can look very low quality-ish if they are used in over-abundance).
But I do have to give them props for the prints on the Villains, which I wanted LEGO to make for a very long time, actual demon minifigures even tho they are executed badly storywise.
The story, thematic aspects, and character tropes are rehashes of what was before. Ninjago for the medieval setting and theme with futuristic tech while also having magic in (its just the western medieval stuff rather than the eastern stuff, but its still medieval which Ironically is how Ninjas were first created, as a sub-theme of Kingdoms, a medieval line). If they actually wanted to make something interesting, they should have at least tried to tie in all the Knights Kingdoms lines into the chronology of this world, because it would work for this world, while also giving nods to the previous lines, and also enriching this one to boot.
Again, the main gripe for me with LEGO was always their lack of a good narrative focus within their lines, which dont try to do something innovating with that. The closes were Bionicle G1, The LEGO Movie, and to some small extend Ninjago.
