No matter who staffs CTU, things will always be the same. Jack and Chloe will have to work on their own, everybody will spy on everybody else, the Director will know nothing and be completely useless until s/he's replaced by someone from Division who knows even less, at which point the former director will almost look good and later get a noble death, and, most important, never forget that all CTU romances are doomed. DOOMED. (I call blonde girl dies.)
Do something different, show! Otherwise, why are you on?
