You are right.
And thanks to the poster about the Axe Man history -- I knew some of the facts behind Lalaurie and the real voodoo witches (I have to wonder if any of the relatives of LaLaurie's victims, or even her family, if there are any known, were upset by this season? They probably didn't care...)
As usual this season, the AV Club's review is spot on.
http://www.avclub.com/review/go-to-hell-107108 I particularly liked this note:
o illustrate the problems with the season, let’s take on LaLaurie’s character arc: Historical serial killer. Made immortal and buried beneath the Earth for centuries. Dug up by Fiona. Made a maid for some reason. Daughter resurrected as a zombie. (Actually, up until this point, it sort of works.) Becomes sympathetic to Queenie. Sold out by Queenie. Becomes an animated head. Goes back to being a serial killer after being reassembled. Takes over her former home. Made mortal again and killed. There’s nothing even approaching a coherent throughline there, and you can extend that to everybody else on the show.
At least Kathy Bates seems to be having fun, right? Lance Reddick, too. He’s having the time of his life, and who can blame him? And Lily Rabe is really good at stage combat, so that’s something!
(And I know, why I am I even still discussing this show... I felt as ridiculous complaining about the last few seasons of Nip/Tuck. I hate the term hate watching, but Murphy, more often than not, seems to bring that out in me.)
