I still don't really understand where the connection comes from that "having a love interest" = "trying to appeal to female millennials". Having a love interest, even a love triangle, is a fairly standard storytelling device. And you just said it's "not bad". So, who cares?
I think you're looking for a fight that's not here.
It's not "love interest = X" it's the sum of it's parts. Again, the similarities to a spoof just a week or so ago should tell you all you need to know. There's nothing exactly "bad" but I don't see anything particularly good either. Nothing that shows me they have any new or interesting ideas for the show or character that would warrant the positive reactions of the thread.
Again, I'll watch and see and hopefully it will impress.
