Dragon Ball and Dragon Ball Z weren't that great either, we're just nostalgic about it from our child / teenage days. I mean, anyone complaining about Freeza or 17 or whatever forgot that Goku oficially got 1,666 times stronger on a single day, back on the Freeza arc.
However, it has been spiraling downwards on plot, characters etc. ever since the Boo arc, so I guess Super it's just an evolution of what began to happen back then, with some cool moments and concepts here and there, such as Hit and Goku Black.
