I think I had similar impressions. Loved the fast pace, great animations, the plethora of references to all sorts of games. It's a nonstop audiovisual treat of a nostalgia trip.
Thinking about it after, some of the plot really makes me mad. Mainly the backstory of Bowser's bed time story to Jr. Other stuff like that, everything that happens just happens or gets moved on by the dumbest, hollowest reasons. There's no excuse for the choppy story. It can be for children, it can be action focused, but the little bit that is there doesn't have to be frustratingly vapid.
And yet... I come away overall really liking it. I'd hoped I could say without caveats that it was great, and I can't. But I was smiling the whole time, and it didn't overstay the welcome.
Might be that OP is super awesome or just lucky. I'm no sort of authority, but all the layoff headlines I'm seeing lately make things seem so dire.
