Just finished watching episode 1 and really enjoyed it.
As someone else mentioned, it's edited in dialogue only, so you still see the sign for "Satan City". Aside from that, I only really noticed Roshi's Blu-ray joke being about movies in general rather than dirty movies. Stuff like Trunks beating up the snake was left untouched, so that's encouraging.
And the opening was obviously shortened a little. Interestingly it had SSB Goku instead of SSG in the part where the form flashes over him, so it must be opening 2 instead of 1. I was also surprised they left in the eyecatches, as all previous UK broadcasts of DB/Z/GT and Kai removed them, likely for commercial time. And there was another cool promo during the adverts. All in all I'm very happy that this will serve as an introduction for a new generation of UK fans, while also pleasing us old ones. I'll definitely keep watching it live when I can, and will record it on my Sky box when I can't.
19 years ago I was rushing home from school to watch DBZ on Cartoon Network, and today I've rushed home from work to watch DBS on Pop. I guess it's true the more things change the more they stay the same.
