The trailer looks like typical kick-butt, kick more butt, kick even MORE butt, then if there's anything left, ask questions and take names.
HOWEVER(!!!!!!!!!!!!!!!!!!!!!!!!!), some back stories I've read in the current TV Guide have me seriously concerned that the writers have either jumped the (political) shark, or one of Aaron Sorkin's minions has invaded the writer pool. Not to give too much away, but President Wayne Palmer has a "conservative adviser" (Peter McNicol, of "Ally McBeal" and "Num3ers" fame) who is described in the write-ups as a whacko whose enemies think he "treats the Constitution as a series of suggestions".
On the face of it, this may mean little, but the fact that TV Guide is highlighting this character and his "quirks" has my B.S. antennae humming at full tilt.
24's staff is split politically, so it's pretty balanced. But thank goodness they don't have any Michael Moore inspired material.
