Some things were good others weak
Weak stuff: Luigi sounded like Indian not Italian, Mario was a bit homosexual which is in my opinion gay, Princess behaved like Avril Lavigne and her voice was louder (shes a girl, men speak usually louder its biologics mate), the Intro Credits were so freakin long and I got sleepy, Mario should have died in the end because he is a fucker, Luigi should have more credits as he is the older brother and the poor guy received a role as an Indian while he only knows to perform as an Italian.
Good stuff: there were nice jokes and the fighting scene between mario and bowzer was hilarious! As the chap said earlier the wip sounds was a good joke and very original, the way Mario is a smartass was funny a bit Inspector Clouseau-like. Hip Hip and hooray messed with up up and away was lolol but not lololololololol, but still had a lol so its okay.
Cant say its bad because its not, its a good animation perhaps the fact that im sleepy may have compromised the evaluation but you still have got a good grade which is 8. Peace mate.
