For the first two arcs, I say just avoid them and instead watch the movies. The movies are awful, sure, but you can get it over with much faster this way.
Yeah I watched the movies and didn't dislike them anywhere as much as the series
For the third arc, I don't know. Never watched it, never cared to, but people seem to like it.
This is exactly what I did
I kept skipping episodes to see if things would really pick up and get a bit better
And for the last, I think it is totally worth it. At its worst it is silly and bad in a harmless way, but at its best is legit fun and good fanservice because why not.
Some of it seems fun
But it's just not what i was really wanting from a dbz follow up, I dunno
