Try actually looking at screenshots of the first NSMB compared to screens of this. Notice that everything is made of polygons, and at a 5th gen amount?
This game has nothing of the sort. Just compare the Mario models from the two games. Either Mario has a higher polygon count and more detailed texturing, or he's a sprite. Either way, this is not the same art style and graphics of NSMB.
A flashy-first game is awesome when it comes out. A great-first game is awesome forever.
Plus, just for the hell of it: Kelly Brook at the 2008 BAFTAs
