8:00 TO 9:00:
This first hour of Thursdays is another busy hour for me, for there are 3 networks that I am wanting to watch TV from.  ABC has the intriguing new series FLASH FORWARD, which is built around the high concept of a billion or more people who all have 2 minute blackout whereupon each person sees something that happens to them in their future.  ABC is priming the show to take over for LOST, but first it has to succeed on its own in this brutal hour.  Competition comes from FOX's reliable BONES, though that show's season finale seemed to piss off some fans. Also, BONES is starting to age, as is CBS's SURVIVOR.  That leaves NBC's new-ish hour of 6 episodes of SNL WEEKEND UPDATE THURSDAY and PARKS & RECREATION.  I think PARKS will come back stronger in the fall now that producers will have had time to retool it.  The darkhouse in this hour is CW's VAMPIRE DIARIES, which should ride the TRUE BLOOD/TWILIGHT wave of vampire success.  Then again, it could become another MOONLIGHT.  Interestingly, Thursday night at 8 staples UGLY BETTY and SMALLVILLE have both been transplanted to Fridays.
FIRST: SURVIVOR (CBS)
SECOND: BONES (FOX)
THIRD: FLASH FORWARD (ABC)
FOURTH: SNL/PARKS (NBC)
FIFTH: VAMPIRE DIARIES (CW)

9:00 TO 10:00:
This is still the week's most brutal hour, though ratings for ABC's GREY'S ANATOMY and CBS' CSI have fallen, and I imagine will continue to slide.  That leaves an opportunity for FOX's transplanted FRINGE (which, along with MENTALIST, move from their cushy Tuesday slots to the more competitive Thursdays) and NBC combo of OFFICE and 30 ROCK to increase viewership.  The dark horse here is SUPERNATURAL, which has seen its ratings increase year to year and, entering season 5, is finally an established hit for the C-Dub.
FIRST: GREY'S ANATOMY (ABC)
SECOND: CSI (CBS)
THIRD: OFFICE/30 ROCK (NBC)
FOURTH: FRINGE (FOX)
FIFTH: SUPERNATURAL (CW)

10:00 TO 11:00:
THe most aggressive move of the season is CBS's decision to move THE MENTALIST to this hour. That means terrible news for PRIVATE PRACTICE, which also had a terribly gruesome season finale.  I will be watching JAY LENO, thank you very much.
FIRST: THE MENTALIST (CBS)
SECOND: PRIVATE PRACTICE (ABC)
THIRD: JAY LENO SHOW (NBC)

TOTAL HOURS I WILL WATCH: Six (PARKS, SNL, OFFICE, 30 ROCK, VAMPIRE DIARIES, SUPERNATURAL, FLASH FORWARD, FRINGE)
