Why people assume that making a new Donkey Kong is lazy or lacks effort?

Because Nintendo has a creativity crisis. All we get are Mario 3D, Mario Bros, Zelda, Pikmin, DK, Yoshi, Kart, Smash...
They even recycle old games of these franchises. WW remake, Super Mario 3D looks like a Mario Bros, seriously, after playing SM Galaxy 1 and 2, 2 of the best games ever made, this is a BUMMER.

I would say the same about Playstation if we'd only get Gran Turismo, Crash, Spyro, Syphon Filter, Twisted Metal and Medievil since 1995. But we don't. That's the difference.
