The 'gritty' Mario YouTube short is almost a genre in its own right nowadays. There's been that many of them, I've sat through dozens. There's a general theme here: take all the cute elements of Mario as a game (power ups, coins, etc) and recreate them in a real world setting. In that sense 'Gritty Mario World' is no different from the others, but for some reason I was still entertained! This is kinda cool!
A lot of it has to do with the production values. It's sharp, funny, well put together and surprisingly well acted. Made in Adelaide, this is one of the better Mario parodies I've seen in a long, long time. Well worth checking out!
