It depends on if it is an attempt at re-booting a franchise or just a direct sequel to an established game.
Case in point, Super Mario Galaxy took a well established franchise and imo, turned it on its head with a brand new setting and gameplay mechanic. Then that concept was further refined and made even better in the 2nd installment. I feel the same is evident in BoTW and TotK.
I don't feel that a franchise needs a complete re-imagining every release, refinements are perfectly fine. Eventually though, as good as a well polished game concept can be, without a re-imagining, it will eventually get stale and lose its lustre. (NewSMB anyone?)
