It's not a bit of a joke though. Some. Not all. I can also agree that a lot that they made aren't up to that level at all, but some definitely are.
People agree and disagree dependant on opinions of course, but NSMB Wii was great, Skyward Sword was great (for me it was better than MM, WW and TP) and even though its not content heavy, Wii Sports was absolutely amazing, such fun to play... and it's the amount of fun and enjoyment games give you that's most important!
In regards to an impact games have had, sure it'll be difficult for them to have the impact of certain titles. OOT, first 3D Zelda. Mario 64, first 3D Mario... its going to be hard for any games to have the same impact as them!
