Meh, the first one got boring and repetetive after just a few hours.
For me, I think it picked up again after you get some of the better powers like with Rabbid Mario who can blow up lots of enemies at once. I hope in this one the abilities get crazy early on. And maybe they can chill out a little on the rather lengthy puzzle sections.
For this being one of the better selling launch-window Switch games, and for how much Ubisoft will never let the Rabbids die even though we are years past the Wii era, I'm actually surprised it took them this long to put out a sequel to Mario + Rabbids.
I really liked that first game, but yeah it did get pretty repetitive, also to date it is still the only Switch game to fully crash to home screen on me (only once, though). And I played it during early pandemic in 2020 when clearly all patching that was ever going to happen had already happened.
