I think this quote, "Copying Nintendo's own celebration seems not only wrong-headed but borderline offensive (Metro GameCentral)," is proof enough that some reviewers never intended to judge this game based on its own merits.
Honestly, this looks like another ZombieU to me, where you can throw out the score. As of right now, there are five reviews that rate it a 90 and four reviews a 65 or less. It seems very much a game that depends greatly on personal taste--and how objective you can be about a new IP that is strongly influenced by an existing IP. Personally, I don't see the point in going overboard with the comparisons when both IPs are exclusive to different consoles, but it seems to be a big deal to some.
Regardless, I think this is yet another game where someone on the fence should read the reviews rather than base anything on the meta-score.
