I am not sure... Something has changed about the show. I don't think it's because of the new character, I think the writing is just different.
The show always killed and maimed women, but this season it feels as if they are going to new heights here. They do kill men, but they never spent a lot of time with that, they usually just show their discarded bodies. It is always women right in the middle of it it, and a lot of time is spent just showing and glowing in their suffering.

I think that has been going on for a while now, though. At least I noted an influx in female victims for the last two or three years. Even when you just hear about a couple being murdered, it is nearly always "the guy got one shot to the head but the woman was shot twenty-five times on top of being stabbed..."

Admittedly, the single cases all blur together but I remember going "seriously, again?" a few times in the last few Seasons.

But I have to agree on especially the episode with the marionettes, it was really, really pronounced with the woman suffering the most horrific tortures and the men just being discarded or the one guy who shared her fate, you didn`t seen anything of what he went through.

I think the show has pretty much played itself out in general and should be allowed to end but it`s already a certain renewal.
