I don't really understand Beerus' point of bringing in Monaka. Like, I get the whole idea of introducing someone stronger to motivate Goku and Vegeta to improve, but... there already are people who serve that purpose: Beerus and Whis. The sayans don't really need a new guy because they've already been striving to surpass the characters that are already there. In light of that, entering Monaka in the tournament just comes off as Beerus sabotaging himself for no gain whatsoever.
And also: Hit's ability is just plain stupid. No, I don't mean the time leap one, that one is ok (initially). What I mean is his ability to just... decide to get stronger. Like, what the fuck. He's just like "until now I've never thought to get stronger, but now that you're kicking my ass, I guess it'd be a good idea", and suddenly his time leap ability is five times as potent. Dragon Ball has always been notorious for its character strength-escalation and power-ups for silly reasons, but this is honestly a whole new league of ridiculous. How do you even defeat a guy who can increase his power by deciding it is a good idea to have more power? I was into the fight until that nonsense happened, then I was pretty much just "yeah, please wrap this up already".
Other than that last point though, the saga was pretty good.
Except for Frost being revealed as an asshat, that one was kinda meh too.
