When I first started breaking up my web reviews into different categories, I was undecided about whether to include one for "period shows," even though there were several webseries that would clearly fit in such a category. I finally decided not to do so, but I always assumed there was a good possibility that I'd get around to it eventually. And now I have. Some of the reviews I've already done I'll leave wherever I originally put them, and just add secondary links to them from this category (if they are of more specific genres). Others reviews, I'll move here. (Some of those I may include links to wherever I had them before, and some I may not.) And of course, now that the "period" category exists, I'll put some reviews here whenever I watch series that fit the category. ...Which basically means any show that's set sometime earlier than when it was made, be it the distant past or more recent (but probably not so recent that the different era isn't a significant aspect of the show).
