Honestly, so long as the writers and actors are invested in the series, I say why not?
The CW’s Supernatural has run for fifteen seasons and Law & Order: SVU was recently renewed through Season 24, so there’s precedent for longevity.
A recent update from Selleck revealed that he was negotiating a deal with CBS for next season but wanted the network “to order two seasons.”
I’m sure viewers would be happy if the show had been renewed through Season 12, though they’re likely still happy with its recent renewal for Season 11.
