I actually don't think games should be priced down because they're re releases. People are always complaining about slapping a full price tag on a non-brand new game though, so it's a common complaint. I must admit I thought that extended to reviews but I was wrong.
As for the "anyone but Nintendo" rhetoric, what youve got to understand is that it's not anything against Nintendo. It's against the press. Games like Skyward Sword got "classic level" reviews when they came out, and 3D World is the same. Not that 3D World is a bad game, but generally people look at it in the context of other games and other Mario's and say "not up there with the classics". And yet again top tier reviews. Looking slightly down the scale, Metroid other M a great score of 79. Pikmin 3, great game. One of the best of all time? Scored 87 on mc. That's nearly Horizon level. Maybe it is just that Nintendo makes much better games than every other developer, but it just looks like Nintendo games get scored on a different scale.
