Tbh it was just alright. I liked Cyberpunk Edgerunner way better than this, and Arcane is in another galaxy.
The main character simply wasn't that interesting imo, none of the main character were. The "princess" was out and out annoying and her "arc" slowed down the main story.
The only truely interesting thing about the show was the European guy, Ebijah. He was essentially the Emperor Palpatine from the Star Wars prequels, just evil and loves it. The minimal depth about his sister only added to him, where as a child he tried to have his sister survive by drinking his blood, something that humanizes him as broken and not simply evil for the sake of it.
