Omg SQ is such a disaster tho. It gets less viewers than AHS on FX. When they said AHS meets Glee, they probably meant Glee after its peak when it was literally dying.
Anyways, Scream Queens is flopping because they are against Taylord. Their main market is literally Taylord's audience, kinda dumb to trash her and her fans tbh.
Empire has better story-lines than Glee, but Glee at its peak had the better music. Most of the music on Empire sounds pretty dated (probably because Timbaland produces it all)
