Cooler was also almost a complete repeat of the Freiza saga down to exact details being the same. Broly was literally ripping off Broly wholesale just cuz "muh canon." That isn't anything new for the series, as most of the movies for DB were rehashes of the main show cut down to feature length.

I enjoyed it just because it was still a bunch of higher budget action sequences than anything Super is capable of putting out, and that's all I'm interested in the series for.
