If I were in charge...
I'd admit that
FlashForward's basic premise is shallow and gimmicky. If I didn't like that, I'd do another premise. Given the choice, I
would do another premise, but let's assume I'm not being given the choice. So I'd embrace this gimmickry and make the most of it.
The sole interesting thing about the show is that you have impossible scenarios that, if we assume predestination is ruling this universe, are "impossible." A main character (who we assume is important enough not to be written off the show) is going to be murdered. A seemingly faithful wife will be unfaithful. A determined recovering alcoholic is going to fall off the wagon. An almost-infertile woman is going to become pregnant. A father's dead daughter comes back to life.
The gimmick is, how will all these scenarios turn out to true anyway? Clever writing could create a path for all of them to be true, because what we think the flashforwards represent isn't the case at all. There's another explanation for all of them, or at least most. Some of the writing doesn't even need to be all that clever. The "evidence" that the daughter is dead could be concocted - deliberately swapped DNA plus an eye witness who didn't bother to check for a pulse.
The thing I wouldn't do is just to throw up my hands and declare the premise unworkable and decide that none of the above is going to happen because predestination isn't ruling this universe after all. Then you loose the gimmick and the reason for this premise to exist in the first place, and you are left with only the characters and the mystery of what caused the flashforwards to interest viewers.
Neither of those elements is strong enough to carry the story - the characters are mundane TV types and the mystery of the flashforward doesn't much matter anymore if the flashfowards are not even going to come true. Then the story is about the world having some hallucinations which have some percent chance of coming true between 0% and 99%. If the percent chance is, say, 5%, then who gives a flip? If the chance is not 100%, then how do we know these visions are anything for anyone to worry about at all?
So the short answer is, I would try REAL hard to get myself another show, because this premise sucks, if the best you can get from it is gimmicky "clever" writing. Not all premises are worth the effort to craft stories from.
I like how FlashForward drags on after 6 episodes, yet it took 2.5 years for LOST to get anywhere.
Lost has characters who are far better than mundane TV types, and even if the writing was incomprehensible for the first 2.5 years or so, it was creative and amusing enough that they could get away with it. All that nonsense about pushing the button, for instance - what complete BS, yet incredibly entertaining!
If
FlashForward could do that, I'd probably take the same attitude as I did with
Lost - perfectly patient to be entertained while waiting for explanations. But when I look at the TV landscape, I see how rare that is. Most shows are like
FlashForward - middling characters, middling writing.
V, for instance, is very much in that mold. But the premise is a durable one - alien invasion OMG OMG OMG!!! - so if they frak
that up, they should really be ashamed of themselves. Given the choice, I'd jump ship for
V, the show with the much easier to execute premise.
am I to understand that for all the worldwide hype of Flashforwad the show is failing? and I was totally right not to bother with it?
Oooh I dunno. It's better than most of the crap on TV - police shows, doctor shows, sitcoms. And even if I think the premise wasn't something they should have tackled, I'll give them credit for trying to tackle a tricky premise in the first place. Check it out, see if it grabs you after five episodes or so.
And there are some unfair criticisms in this thread:
1.
No private lives for the characters. Well, I'm not wild about the soap opera either, but to just focus relentlessly on the characters as being defined
2.
We need scientists. We do have scientists. They're the "bad" guys. But at least we have a sci fi show with scientists at all, that's progress.
3.
Too American. The aforementioned bad-guy scientists are both British. Well okay, they're bad guys. Blame Disney and George Lucas for warping our tiny American minds.

But seriously, they can't diffuse the action geographically; they could have FBI types from all over the world descend on the LA office to keep the action focused on one place, but it would still be in LA.
