The manga has had a problem with the past 2 arcs, including this current one, being shit.
It's kind of sad that the only redeeming factor that came with this arc is Frieza reappearing and one-shotting the supposed "strongest in the universe" and even this plot development itself is a really bad one.
But because the arc itself was just slogging for months and months on end (longer than that honestly)... an otherwise bad plot device makes it more palatable.
Either way I feel like Frieza is way too over exposed.
