As a longtime fan of the original animated series and the comics, I really like what this show brought to the table. And I felt like it got consistently better as it went along and the world started to open up.
Overkill ultimately became one of my favorite characters. Ben Edlund is great at sending up the brooding loner dark vigilante bad guys. I think the comparison to Venture Bros. is very apt. It does have similar sensibilities. Overall, it felt like a fun slightly comedic reinvention of modern cinematic superhero origin stories. Like it didn't step over the line into outright parody. More like it was having fun with those ideas and peppering in some more comedic things in there.
Also how can you not love Danger Boat?
A lot of interesting possibilities for season 2. Unless I'm mistaken, I believe it could turn out that Superian or AEGIS are in fact the real bad guys. Or at least not quite so benevolent as they appear.
Also Arthur's stepfather.
I guess my one criticism is that I think they went a bit overboard with Dot to make sure the one significant female character had agency in the plot. I guess my criticism isn't that they had her becoming so important and going on the missions, but that was after she was so dismissive of Arthur and his beliefs. She was basically reinforcing the idea that he was crazy and didn't want to let him forge his own path, and she was never all that apologetic about it. I don't feel she really redeemed herself before she made that transition. At least something like, "Sorry I didn't believe you Arthur. You're actually pretty amazing." Something like that would've been nice.
I kind of hope they avoid making Dot into a superhero as well, but we shall see.
