Here's an interesting conundrum. I'm reading a screenplay by a very competent writer. He's set up a situation where the hero is being menaced by thuggish people and there's no one he can turn to. He's helpless. That sets up, I assume, the basic problem of the screenplay.
My problem is that when the hero is jammed in a corner like this and all he's going to be able to do is suck it up, while I sympathize, I don't particularly want to spend more time with him and his problems. It's a pure downer. But it is dramatically effective to place the hero in a real jam.
What I'm suggesting to the writer is to make the thugs more fun to watch. They're brutal, but they're not much fun. I think we need them to be quirkier, stranger, more fun to watch. Think of Gary Busey in the dress in
Under Siege: he's another insane killer like Mr. Joshua. But he's an insane killer
in a dress. (Which of course makes it brilliant when later, just after he's murdered the captain, he notices that his efficiency report recommends him for a psychiatric evaluation. Still in a dress and makeup, he turns to Tommy Lee Jones and says, "Do I look like I need a psychiatric evaluation?" And Tommy Lee gets to do his patented raised eyebrow and say, "Not at all.")
Another direction would be to give us the full humanity of the thugs and give us a sense why they're beating up the hero. We still won't like them but at least we're getting insight into them.
Be efficient in setting up your jeopardy. But don't be so streamlined that there's no fun in it for the audience. Make the villains fun to watch even if you wouldn't personally enjoy their company.
Also, don't let your hero ever be completely helpless. Helpless is a repulsive frame of mind. No one wants to be around helpless. Even if your hero is getting killed, at least he could try to josh his way out of a bad situation. Or fight against the odds. Anything that tells us he's not a loser.
