Funny female leads, isekai (mostly)

It is funny at first, seeing of the FL survives and tricks the princes and the king with her "kindness/pure / innocent - sister/daugther act".
Also a intresting plot to see a modrn woman surviving in a even more ridicolous gender discriminating society.
However, with time it gets a bit cliche and the strategy by the "villains" and the "heroes" are quite obivious and easy to see through.
Which leads to everyone seems a bit dumb.? In my perspective
