When FlashForward was picked up for a complete season, it was also given a 25-episode order, 3 more than the normal 22-episode pickup. Slowly but surely, the number was whittled back down to 22 as the ratings plummeted. It's hard to blame ABC for anything. FlashForward was given ample promotion but the ratings fell each week due to viewers thinking it was totally stupid (which it was, of course). Before someone starts yapping about the hiatus, take a look at the ratings. The hiatus had minimal effect on the ratings; the vast majority of the decline was before the hiatus, when there a continuous run of episodes.
Even with all the adjusted schedules, the producers (who were switched several times) went right on with their game plan, not really tightening the overall narrative, until we're left with the finale, an anti-climactic mess that ends on a bizarre cliffhanger. So basically, it was typical FlashForward.
I have no clue why I stuck around to watch. Maybe it's because I wanted to see the ending but if I didn't watch the series finale, I wouldn't be missing much. For the most part, the flashforwards turn out to be true except for minor changes. The biggest differences are Mark shooting up the invaders, Demetri still alive, and Nicole not killed.
And lastly, the second flashforward, a heavily stylized set of images amounting to nothing discernible other than Charlie saying "they found him," in the end. I assume she means Mark who is in the FBI building when it blows. *Yawn*
Score: 7.4/10
