After a 15-week hiatus, Prison Break finally returns to Fox this Monday night.  Although the show is returning to its old day, its being welcomed to an earlier time (8pm) thanks to the old veteran, 24.  When we last left the show, Michael Scofield and his fellow inmates were on the verge of rescuing his brother, Lincoln, from the electric chair.  Of course, a wrench in their plan looked to foil everything and left viewers with a nail-biting cliffhanger.  Will the prison break ever happen?  Of course, it will.  But the bigger question is—will the show be able to regain the momentum it had right after its heavily-hyped fall debut?  Out of sight usually means out of mind, but being partnered with action hit, 24, could give the CBS comedy lineup some nice competition.
