If I had known this season was going to be airing two episodes a week instead of the usual one, I would've kept up with the season better. I don't like this new trend that Prime is doing with two episodes a week. They did it with Hacks and The Marvelous Mrs. Maisel, too. They keep changing from full season to weekly to two episodes weekly that it's hard to keep up with and it's pretty annoying.
That said, considering all of the madness of this season, I suppose I'm somewhat grateful that it took me this long to catch up and just in time for the last two episodes.
I've enjoyed most of the season from the big mystery regarding the Sparas (a creature created for this show?) and Tourmaline's terrible connection to it to Agreus and Imogen's adventures with the New Dawn standing in for the Russian Revolution, complete with the wonderful Joanne Whalley stealing every scene. Some great character arcs for Darius, Runyan, and Berwick in addition to the aforementioned characters, with a few surprising deaths midway through the season. As much as I like Vignette, I'm pretty much done with the back and forth nature of her relationship with Philo.
However, I've been less of a fan of the heavy horror elements of this season, most notably the level of gore the Sparas inflicts and its actual appearance. That's the kind of thing that immediately put me off of Penny Dreadful even though I really wanted to like that show (yes, I get that's part of the draw of that show but I don't like heavy gore).
I'll hold off on detailed thoughts until the final two episodes and when everyone else has also caught up. Seems like we're all going at it different paces.
