I mean, I agree. Dragon Ball was always following the principle of "fast, stronger, better". Majin Boo had been presented as the ultimate danger of the universe, and Goku beat Boo. What else is left there? The introduction of Beerus is nothing but a plot device for making a move to another universe. Because thatīs what needed to happen.

I honestly try to come up with a different direction, but Iīm drawing a blank here. I mean, there a some ideas, but theyīre either too elaborate for Dragon Ball or they donīt focus on Goku, which seems like a nogo. For example, Iīd love if the story focused on humans again. As I mentioned before, seeing how Kuririn is the strongest human being, it feels as if mankind is one of the weakest species in the universes, fighting power-wise. All those other species we met either have more base power or can transform. Humans? Nothing. Would be awesome to make it so that Kuririn could fight together with Goku again.
Another idea would be to focus on the realm of the dead. Back in DBZ, we learnt that when you did while being dead already, you completely vanish. Tbh that doesnīt make sense. It sounded more like they donīt know what happens if you die a second time. So thatīs something they could have followed. Have Goku die while being dead, and there you go. Would be full of real drama and seriousness, too, because all his friends would grieve for real again. But as I said, thatīs probably too elaborate for Dragon Ball.

Considering all that, DBSīs story, while not well executed, is the logical consequence of past developments.
