Kind of stupid and pointless
Then again it is probably for children under 12.
Mario brothers started as failures, and by the end I think they still are. I don't think they learnt anything.
Princess Peach brought destruction to her people, and there was no self sacrificing act. Everything was OK by the end because things just happened.
I watched, there were a bunch of activities, I wouldn't say it was boring, but that is just about all I can say.
