I had mixed feelings about it actually. The art style was hard to get used to and definitely look of Alfred but that's because of how i often view the English Butler. I associate him with baldness (Not shaven) or very short and neat grey-ish hair plus a mustache. It was weird to see him more like Agent 47. Though it does sound kinda cool on paper, 47 as Batman's servant. 

I really didn't have anything to say about Katana. Found her rather boring and the Villain roster was...questionable. I guess they may have been having Brave and the Bold thing where they were more focusing on lesser known characters but it felt like they didn't do enough with what they had and it felt like there were various Iconic Batman Villain shaped holes that weren't being filled. It felt...too restricted in my opinion like they were holding back.
These first 11 episodes were bad, per say. But they weren't that interesting either. I watched them all and I wanted to see something more being done with it. Infact, I was looking forward to what they would do with the Joker because it was going to happen eventually.
