Inconsistency in the story and levels prevent the score from going very high, even though you gave it an 8 (I assume out of 10)?
That was a terrible review. You basically said nothing other than "POOR CHARACTER DEVELOPMENT ALTHOUGH NOBODY EXPECTS IT TO BE GOOD" and "I COULDN'T FIND THE LUMA." You didn't even touch on any of the levels other than the 'toy level' and never mentioned boss battles. You didn't talk about any of the interesting mechanics that were in place. You didn't talk about Mario's different forms. You didn't talk about the racing level(s). You didn't talk about the controls. You didn't talk about the graphics. You didn't talk about the music.
Final Score 2/10
