I can see the issue on both sides in this discussion, and why it could be problematic for both sides. On one hand, I'm fucking thrilled that Jessica Jones is going to have a season directed by just women.
Last season, Jessica was reeling with PTSD about her abusive, mind-controlling boyfriend who raped her over and over again and made her do things she would have never done, and while last season was fantastic, who knows, perhaps if that season had been all-female directed, it could have sent a stronger message or done something better. Women are more likely to experience sexual harrassment and these kinds of experiences than men are starting from a young age, and I do think a woman who has experienced that and knows how it feels could bring an extra element than say a guy who knows it's wrong but has never actually endured it. That's not to say guys don't experience it, because we do, it's just a helluva lot less often and typically trivialized by other males (but this is a different subject altogether).
That being said, if they decided to go with a direction for the Netflix series by, say, having an all female-directed Jessice Jones and all-African/African-American directed Luke Cage, I don't really think they would be that unjustified to keep Daredevil with the directing team it currently has since I do think asking for them to have a wide and broad range of directors for one show but then allowing a different show in the same universe and company to have only a certain type of directors for it's show is kind of contradictory.
That being said, I do also think the directors should only be chosen if they have earned it as well, but let's also remember that it's been proven just how hardit can be to actually land directorial positions in Hollywood, be it for film or TV, when you're a woman doing it for an action/comic based show, or a POC in general. And while we have seen non-female directors do a fantastic job in Jessica (I have yet to watch Luke since I am making my way through S2 of Daredevil currently), who knows, maybe a female director could have come in with an first-hand experience of what Jessica went through and made it, overall, a stronger episode without having to make it feel like they are beating you over the head with it (as we've seen from other projects where a director who has never experienced a form of discrimination/abuse like that can make it more preachy than realistic).
Plus, it opens the doors to give more opportunity for female directors to get their debut or even make a much bigger name for themselves when it's already so hard to get a directorial job in the first place.
So I dunno, I'm completely for it, I'd love to see what it brings to the table, but I also do think it would be unfair to expect Daredevil to heavily diversify it's directorial team if the directorial team for Jessica would remain all-female for more than one season (and if they did something similar to Luke Cage in the future). Not saying I don't want a diverse team for Daredevil (maybe if we had one, Night Nurse woulda been treated better), but I just feel it would be contradictory to allow one show to get away with it, even if that show is doing it for better representation and a potentially more authentic voice, while another has to have a wider range.
But again, that's just my two cents.
