Jack's kinda been annoying me for the last couple seasons...the character's just gotten smug and routine. He was more fun in the beginning.

(Also, the Jack/Jo storyline? ARGH. Though I do appreciate the way the actors have acted it physically; of course Zane immediately picked up on it in that one scene where Jo was worried about Jack being hurt. Still. ARGH. I enjoyed them a lot more as friends who hung out drinking beer at Jack's house.)
