it suffers from what alot of animated features and cartoons in that the plot moves super fast. characters arent given time to think or process situations, things keep happening without pause.
the moment toad meets mario theirs nothing like "waoh who is this different shaped person?" its "oh hey stranger youre my best friend now let me take you to my leader just because 🤪" similar to when peach meets mario too
i think the thing i like most about it was the visual eye candy, seeing every mario reference and listening to the music. (which im thankful that my friend found a fan edit for that had the original score and not every pop song your mom and dad know about)
