I was so upset when CBS switched the show from Tuesday to Sunday, because switches are usually the death of good shows--but it seems to be holding strong
Opposite. Show is struggling in the ratings for CBS standards. It was renewed because of its critical acclaim and it needs one more season for syndication.
It should be moved to Fridays and paired with Blue Bloods. It would do well, for CBS standards, on Fridays, and it could last for a number of seasons. Fingers crossed!
