I just thought Keifer was EXCELLENT, EXCELLENT, EXCELLENT in this role! Love the entire series, altho a bit violent at times. But I guess that makes it realistic.
I just watched in on Netflix (2012) - the entire series - it was hard to stop watching and make myself go to bed.
But Kiefer was perfect for this role and just did an outstanding job as Jack Baur.... don't know how I could say more!!
