I know not many watch 'Arcane' but I have to say I've not seen better sci-fi depiction overall anywhere on the screen, which took me by surprise. In the latter stages of the second (& final?) series, it stood out. Full of imagination, it seemed like they went all out with it being the last season.
For the overall story, though, it was a mish-mash of different concepts, the first series vastly different to the second, then a switch up in that switch up! As someone who doesn't know 'League of Legends' I think the show rushed itself and the audience that is uninformed about the backdrop never gets to know what's going on.
Shame, really.
