I can understand that but if you love DBZ, i think you'll at least like DBS. Of course, nothing can top DBZ simply because of nostalgia. You can even skip like the first 26 or so episodes of DBS because they are literally an extended version of the movies Battle of Gods and Resurrection F. However, they have made these episodes very funny so i think it's worth watching these 'extended' episodes.
I'd say my biggest issue with DBS is that they seem to be in a rush overall. Many people get too much power easily. Story pacing also seems to be going rather quickly. And if you're not paying attention it will confuse the sh!t out of you because there's A LOT of time traveling involved in the 2nd season.
Besides that, i think its perfect. I's say it's an excellent follow-up. You gotta remember we are all grown up now and we have watched many movies/animes and have been trained to pick out the bad. At it's core, it's what DBZ was when we were kids. So now when younger audience watch it, i think they'll love it. There's no "extended staring" power-ups like DBZ had. Which was everyone's biggest complain of DBZ. They have almost no powerup scenes like that (hence why i say it seems rushed when they power up right away) They do have those filler episodes here and there but they continue the story and are genuinely funny, just like DBZ. That made me appreciate DBS more. And the animation is fantastic; there's more fighting than you can ask for and they are epic! I would watch it simply for the fighting alone.
Anyway, i'll let you decide
