I for one just hate how much shit you have to do in DKC. There are so many controls that you have to juggle all at once.
In Cuphead, you just move, jump, shoot, and duck. In DKC, you have to
>move
>jump
>duck
>roll
>carry shit
>move with animals, some of which have charged attacks
>shoot with some animals
>shoot, then activate a web platform with the spider guy
>throw your partner (in later games)
>switch characters if you want to kill certain enemies
>blow in the Returns/TF
>probably some other bullshit in Returns/TF, I haven't played those games very much
And they all use different buttons all over the controller. None of it feels natural the way that, say, rolling in Sonic or taking off with a cape in Super Mario World does. Yoshi's Island has a similar amount of nonsense.
