The world blacks out and sees a glimpse of its near future. It was a good premise, yet here we are a few months later and “FlashForward” has been canceled. What happened?

Ratings were strong in the beginning and kept falling throughout the series run. ABC shelved the show for a while during the Olympics, but ratings continued to plummet when it returned.

Generally, I enjoyed the show, but grew a bit weary at times, largely because I really didn’t feel that there were any characters worth rooting for. Mark Benford (Joseph Fiennes) was supposed to be the hero, but he was always so angry and serious all the time that it was hard to like the guy. Everyone was so weighted down by the emotions surrounding their flashforwards that no one was happy. Moreover, no one was funny.

“FlashForward” made me realize just how important it is for any show, even a drama, to have a good sense of humor. Think about the last few great dramas — “Lost,” “The Shield,” “Mad Men,” “Breaking Bad,” “Battlestar Galactica,” “The Sopranos,” hell, even “The Wire” — they all had moments of hilarity. Can we say the same about “FlashForward”? I can list several funny moments for each of those aforementioned shows, but I can’t think of a single funny moment in “FlashForward.”

That said, I gave up on “V” but stood by “FlashForward,” yet the former has been renewed while the latter has been canceled. I thought the storytelling in “FlashForward” was far superior to “V,” but that’s not saying a whole lot. “V” doesn’t have a sense of humor, either, which is why I deleted my season pass.

With the departure of “Lost” and “Battlestar Galactica” and the failure of “FlashForward,” sci-fi television is struggling.
