My script is an action/drama/thriller, and a lot of those have scenes going back and forth between the characters. Mine though, even though I'm not finished yet, only have three scenes without the protagonist in. I don't wan it to be too much of him, and not enough of other sides of the story going on, but the story is just made up in a way, in which a lot of it occurs from his point of view. Plus he's the one doing most of the running around, and has the most to do. Could it be a problem if he's in that much? I know it's been done before, but a lot of thrillers do the back and forth thing now.
