all flashbacks do is ruin the flow of the tv show. If you got a good story to tell then you dont need flashbacks or flash sides ways. Keep it simple with a good story.
I disagree. Lost
handled flashbacks perfectly. The flashbacks always served a purpose, to show life before the island, to explain why characters were on the plane, how some of them knew one another; in short, to shed more light on the background of the characters. As for the flash sideways, not using them would not have allowed the producers and writers to tell the story they wanted to.
