There is a lot of *good* here. In fact, there's been three recurring B plots winding through the last twenty or so episodes.
- Chi-chi on Earth, worried for Gohan and trying to mount a third expedition to Namek.
- Bulma meeting and being taken over by the Ginyu frog, and his attempts to battle Piccolo/Kuririn/Gohan.
- And now, the remainder of the Ginyu Force on Kaio's planet.
These scenes, almost unique within Dragon Ball up to this point, are also structured as traditional "B-plots". We don't need a fully Bulma-Ginyu episode, but we get several updates on them in five-minute bursts over a half dozen episodes. That there are three recurring plot lines is excellent.
But... seriously... nothing hangs together at all. The editing is scatter-shot. They build up to scenes and then fail to deliver. They could have fleshed out all of these arcs by simply not having so many unnecessary flashbacks. (Some of which are literally to 1-2 episodes ago.) There are some really decent ideas, executed very poorly. I WANT to see the team try to deal with Evil Bulma for a bit more than 30 seconds. I WANT to see Chi-chi's rescue mission. I suppose I'm probably the only one, but it would have been a heck of a lot better than Goku-Freeza powering up and feeling each other out for ten episodes. And how many times must Gohan almost run off to fight with his father, only to have Piccolo tell him that he has to stay. Too many.
(That said, I did enjoy Piccolo complaining that Kaio kept the Genki-dama from them. That's at least in character. It would have also been a nice time to comment on how no one else learned Kaio-ken...)
