Probably, anyway. Reports are the show will go away after this year, thanks to declining ratings and rising costs.
Yea, it's about time. The show ran out of ideas years ago, especially since there are only so many terrorist attack scenarios/nationalities of villains that can be plausibly used, and the show long ago started repeating itself. And the 24-hour, one-day, real-time structure had a high-enough degree of writing difficulty as it was.
There's allegedly going to be a movie, which I suppose could be good; they just need to take the time and write something good, that isn't just a two-hour episode of the show and is actually something special and memorable.
