dismay and a question

I have not actually watched Downton Abbey and have no intention to, but yesterday I learned, through other sources, that (sort of spoilery I guess):(skip) the only queer character is a selfish, amoral villain.

Has anyone perchance critiqued this approach? I feel like what I've mostly seen all over the internets is either "OMG Downton Abbey is so great, yay!" or "Downton Abbey is a silly soap opera," but no "Let's talk about problematic and stereotypical representation." Admittedly, though, I haven't been looking for it.
