Yeah, i'm really iffy on this season, i feel like the stories need more than half a season to fledge out. The vampire half doesn't make sense biologically, know its a fantasy, but vampires have already been established in Hotel, so this must occur in one of the other ahs universes.
And only 4 eps to tell the whole alien story. The pacing of it will be shit.
They had 2 years to write a really good season and they gave us to mediocre seasons smashed together.
