I haven't seen Poker Face, but it sounds like the writer is saying:
It's great to see a female-led mystery series that is a mystery series, first. People aren't constantly reacting the the lead as a female detective but as a detective.
A lot of content with women leads is ABOUT the experience of being a woman. Content with male leads is not usually restricted this way. And when male-lead movies, books, TV shows, are very much about masculinity (Breaking Bad, Mad Men), they are considered "for everyone."
Masculinity is a topic that applies to everyone. Femininity is a niche.
Similarly, we see this in the way genres are discussed. Without fail (please let me know if you have an exception), when genre TV is elevated to "prestige," it is a genre that is not considered feminine. Usually, it's a genre that is explicitly or historically masculine. The Last of Us (zombies / horror). Breaking Bad (crime). The Sopranos (mafia). The Wire (crime/ cops). Cause stuff for/about men is for everyone. And stuff about women is for women, and people don't take that content seriously.
As for the show itself, sometimes I want a more gender neutral experience, sometimes not. It's nice to have the option.
