one of the issues that AHS has suffered from for a while is that it's being too formulaic with its characters. the novelty of using the same actors between seasons was cute at first, but it became boring after you realized that they were all playing the same role every season - and because of that, you can't help but compare them
Jessica Lange is nowhere near as convincing as she was in Murder House or in Asylum; likewise, Evan Peters had his highlight when he was Tate in Murder House and hasn't been nearly as good since
all of the recurring cast seem like rehashed versions of characters they've been before, except with an accent slapped on here or a birth deformity added on there. at least to me, the only member of the principle cast who has been pulling their weight is Sarah Paulson, and I can't even enjoy Bette and Dot's screentime because they feel so one-dimensionally written
the only thing keeping me coming back to this show this season has been Dandy, who is an absolutely phenomenal character and is a delight to watch (due hugely in part to Finn Wittrock's amazing acting).
