Mixed.
Character-wise, I don't really like this all "good character that has to look bad only because is totally misunderstood". I would have preferred something more... grey. Not to mention a lot of phrases don't really make sense now, for example the ones from Gaban.
Now, he might start doing something more "evil" down the line, maybe as a pirate. We have to see. I hope he also doesn't go along with Luffy too much.
To summarize, I want him to be a little more complex, a real "Loki, and less tsundere than how he seems now.
Power-level wise, instead, he went above and beyond. I didn't think he could be this broken.
