I really liked the last episode and the series as a whole.
Murder House > Asylum > Roanoke > Coven > Hotel > Freakshow
The series was problematic in parts but overall I think it's mostly been a return to form, I didn't expect to enjoy AHS so much again after FS and Hotel. I hope they keep it up for future seasons and I hope they keep playing with the formula. After three seasons of what felt like a supernatural version of Dynasty, it's nice that they put the focus back on the horror.
