As well, she is not liked by some fans because of the way her character has treated McGarrett by basically abandoning him. (But, on the other hand, the character of McGarrett has often displayed Hamlet-like indecision about his relationships, not that I am suggesting that the H50 reboot is like Hamlet, by the way.)

There are two big factions of fans of the show, one for McDanno, meaning those who favor the "relationship" between the two male leads and the other for McRoll (meaning McGarrett and Catherine Rollins).

It is not easy to track down a lot of this hysteria, much of it takes place on some H50 equivalent to the "dark web."
