I think it was a fun episode. The animation is still great and the world building is interesting. I wonder why demons were choosen to rule over the universe - does the demon realm have something like Kais choosen from the 'normal' realm?
Given that the goldfish doesn't like to let people through, I also wonder how long we will be stuck with the current squad. A few more episodes would be fine to give Glorio and the new girl from the opening some time to establish themselves, but I'm still not invested in them - or Shin for that matter. Shin and Glorio are both too serious, but I guess Piccolo, Vegeta and Bulma aren't helping with that.
It would be hilarious if Vegeta and the others find another way in and we cut to Kibito still trying different PINs for the remainder of the series. I don't think I've seen him with the others during the opening, but I could be wrong.
I'm still interested in seeing some stuff about the old cast - I hope we get some B plot episodes with them. I'd also love a few episodes about Babidi coming in and capturing Dabura.
