A rapidly spreading sickness causes a suicidal teenager to put aside her intentions to save her loved ones.

“A rapidly spreading sickness causes a suicidal teenager to put aside her intentions to save her loved ones.”

Foxtrot, there have been many characters, some quite popular who are suicidal or depressed. The best example I can think of at the moment is Martin Riggs from the Lethal Weapon franchise. In the movies and the television series he doesn’t want to live because his wife died. The audience wants to see that enough that it spawned three sequels and a Fox television show(that was renewed for a second season). Someone who is suicidal doesn’t necessarily mean they are determined to end their own life. It can mean depression and that person being more reckless, with no regard for their safety. ?I think that is what Djhasma was going for.

However, I do agree that the logline needs to better present her state of mind as an obstacle and risk and show the character arc.
The logline fails to describe a visual action. How is a teenager equipped and able to stop this sickness?

Here’s an example:?After her parents are infected and?turn into feral?beasts, a suicidal teenager volunteers for a dangerous mission to recover a cure so she can save her family. ?(28)

This example may not be what your story is but I’ve included my suggestions. What action does you character go through to achieve her goal? Also, why wouldn’t the adults do something? Why must this teenager do this? Not the military, scientists, cops, but this one teenage girl?

What’s the difference? Someone who is suicidal is someone who is suicidal, despite age or their life experiences. Teenagers and other young people are the ones more likely to commit suicide, or consider it. What about the fact that she’s a teenager means her being suicidal makes a bad character, a bad story?
To go back to Martin Riggs, he is suicidal and he’s a cop. A cop, someone who helps people everyday. He cares about Murtaugh and his family even though he’s suicidal. As dpg said, suicidal is someone who is likely to attempt suicide, has suicidal thoughts. While it doesn’t mean exactly the same as “lost her will to live” it encompasses that and since author of the logline described her as that, is likely to more closely encompass her character.
I just don’t understand why you see a teenage character described as suicidal as such a problem.
One more?note, you mentioned that an audience may not sympathize with her if she’s described as suicidal, and while I don’t really agree with that I want to point out that?empathy is a much more effective thing to create for a character. ?As long as the character is interesting and the audience understands why they do something, no matter how bad it may seem, how unlikable they are an empathetic character will keep their attention. I’ve mentioned before the film Nightcrawler. Lou, played by Jake Gyllenhaal isn’t sympathetic, he does things that most people wouldn’t agree with and view as bad, but the audience’s attention is kept because we understand why, we?empathize,?and he does have some sympathetic traits. (Again, I recommend the great video essay which discusses this.)
Now, taking a look at the logline, it is labelled as Horror. So, depending on the action the protagonist goes does to pursue her goal, suicidal may not be the best trait that will make a compelling Horror story. Because the conflict in?Horror movies is often created simply because the protagonist(s) wants to live.?But I just don’t understand why you see describing a teenage character as suicidal as such a bad thing.

“On the verge of?suicide, an insecure teen?is?expected to care for her alcoholic father during a quarentine but when?her father is forced to spend time in close quarters with her polyamorous lovers she must keep the peace to keep them safe and inside before one, or all, of them break out of the apt complex and become exposed to a mysterious illness.” (65 words)

There is too much background at the beginning which can be integrated into the description of the main plot. The description of the character’s flaw doesn’t seem to add anything to story, whether as a character flaw or as a skill she can use to accomplish her goal. Also, the conflict is unclear, and makes the characters seem illogical. If they all know about the illness and that they’ll be infected if they leave, why would any of them leave, no matter how much conflict they have among themselves?

The logline is described as horror. So what is the horror element? What is the character or force that causes the horror?
On another note, how does this concept differ from multiple other infection movies? Zombie movies? It seems like yet another movie about uninfected people trying to avoid being infected, and the main character have conflict between themselves. What does your concept offer that’s different from what’s already been done?
And, as Nir Shelter pointed out, what is the specific goal? What must she accomplish or fail at for the conflict to be resolved? ?A logline should describe a clear, visual action, what a viewer would see on screen, what a producer would be able record to put on a screen.

I hope this helps.
