The ideas in this movie were actually pretty good, but then everything went downhill. The new characters are not developed, Yoshi has zero background and attachment to our leads. Rosalina is not part of the movie very much. Bowser Jr. was a decent villain but all of his henchmen aren't great and I also thought Bowser was pretty poor. The pacing felt very fast and I thought I was missing things. The cameos all seemed very fan service related. As for our previous leads, Toad is fully sidelined, Peach has little focus and poor decision making. Luigi and Mario don't grow at all. They also added a lot of random ideas that seemed so out of thin air like good Bowser or Mario and Peach not being together.
