Having just watched the first 4 episodes of 24 season 8, I have a message for the producers. Fans care only about Jack Bauer doing what he does best: being Jack Bauer.
As such, please stop with the stupid sub-plots (example, Dana and her ex) that only take us away from the mighty Jack. 24 should just focus on Jack torturing and killing everybody with Chloe providing him support....and Renee just being Renee.
Hastings is also such a horrible character I am entertaining high hopes that this is merely a ploy to get Karen Hayes back in the show to replace him. If not, I will be very disappointed.
Let us remember why we watch 24: It solves problems by killing off characters, so hopefully all these shitty new characters die soon. After all, you already killed so many great characters (Buchanan et al).
