Horse shit.
It's unoriginal in terms of format, as the 'mario bloopers' well has been dry for years. It's unoriginal in terms of characters as they are all from various games. It's unoriginal in terms of animation as it uses sprites without trying to create new ones to convey emotions (such as the square white eyes and terrible black box mouth.)
Not a shred of originality in the entire movie. No wonder it's the number eight movie of the week.
