I bet if any NSMB had ideas, inventions, innovations etc. blabla like the classics and World had, people would just go ahead and say "oh we've seen that before, thanks" because those games pretty much offered everything possible in 2D world games. If it's so easy to get new ideas into games that haven't been used before and keep you entertained for more than a few hours, go ahead and do it better.
Even if Nintendo released Super Mario World 2, the real one, with all those ideas Miyamoto had for the first game, people would just see it as a lame sequel that adds two or three things but isn't new.
People should just stick to the games they love, forever, instead of talking bad about every new game that releases because it doesn't appeal to them.
And yeah, I bought NSMB2 and it's not super great. But I don't feel any need to rub it in anyone's face because reviews and opinions of others don't matter. It will be fun to finish and it will be fun to finish it again in co-op mode. No matter what bloggers and magazines want to tell me.
(And be honest just for once: the older Marios are as easy. It may be harder at a few spots due to the slightly worse control feeling but that's it. You'd finish them in no time as well now. Just because you didn't as a kid doesn't mean they weren't as easy. Take out your SNES now and try it. Super Mario World should be the only one taking more time due to its number and size of levels.)
