Bad acting(25% of the sucking), nightmare to film(10%), no idea whether it is kid or adult movie(8%), and not staying close to the actual game (57%). "OOH! LETS HAVE MARIO AND LUIGI RESCUE A PRINCESS FROM A REPTILIAN KING. ITS A MOVIE!" said the directors. The game's so much more than the basic premise. Sure that's the basic plot, but still... Trust me, I'm a physicist.
