I think this season should be the last. It's just not the same anymore. I mean season 8 and 9 have been too dark. The show used to have the lighter scenes with Ma and Pa, at the high school, Pete, etc. Now the show it's 100% dark and gloomy and it's just now a totally different show from what it used to be in s1-4.
I'm a firm believer that when a TV show has been on for so long that it's no longer recognizable to the show it originally way then that means it's time to cancel it.
And now I hear Chloe may not be in s10?! Chlow is the last saving grace of this show at this point.
