The Good: Jack is back. Playing the angle of the chinese torturing Bauer so much physically and emotionally draining him so that he doesn't feel adept at performing his "duty". There have already been signs of this during that interrogation scene(the look Assan gives him after torturing the mole).
Jack going vampiro was probably the greatest scene since Jack killed Nina in Season 3.
The Bad: The new characters just don't look like they are going to cut it.(Palmer's sister, the chief of staff, Nadia).
Assan and Morris are dope.
