Not really. Even though I see it as another rather shameless attempt of making the 2D Mario audience gobble up 3D Mario, it looks like, for once, it's actually taking an approach that might work to some small degree. Obviously not because of the aesthetic style or the carnival-esque soundtrack, both of which seem to have been adopted from the NSMB games (you know, the bad aspects of NSMB), but because of the multiplayer aspect, the branching paths that already appear to be much more common than they were in the Galaxy games based on just the four demo levels we've seen, and (since this is a follow-up to 3D Land) the absence of a needless hub world. The cat suit looks nice, because it looks like the first regularly encountered power-up in 3D Mario (aside from Yoshi in Galaxy 2) that could actually be convenient for offensive purposes, instead of defensive ones and/or puzzle solving.
It does look fun, even though I dislike what they're trying to achieve with the game, and hadn't intended to buy a 3D Mario after Galaxy 2. It won't convince me to buy the system, but I might pick it up if something does.
