Is My Review of Jersey Shore appropriate for school.?

No. If you have to warn people to not be offended, it is not appropriate for school. Aside from the horrifying grammar, your use of slurs most certainly does not help prove a point. Your language should sound professional, but you made it seem like you're just talking. As your assignment is a review, it is appropriate to include opinions, but you seem to have done this way too much. Your opinions should be on whether or not it is entertaining and whether or not it will do well, not whether or not the characters act black.
