I loved the commercial during The Middle that went. This is what critics said at first "Horrible", "how did this get made?!?" and 20 other bad things. Then they went "this is what people say now! "a hoot" "best new comedy".
So ABC knows it's much improved. I don't see it living long, it's ending it's season early and that's never a good thing.
I hope they bring up this little side joke of when the human dad was watching alien health class the video brought up an invasion. That would be a fun arc.
