In the distant future: When a naive teen joins the army, his over-protective biker brother must enlist, go through the harsh training, and find the boy so that he can get him out before they’re sent to battle against nightmarish aliens.

How is he going to "GET" him out? Otherwise, I basically dig it. And "overprotective" is fine as a motivation and flaw for a main character. We've all been there. Relatable enough! :-)

Agree with Nir Shelter.? The logic just doesn't seem to add up.

And somebody has to fight the aliens.? It is a worthwhile cause -- isn't it?? With the naive teen there's the potential for a positive character arc? as he matures in a battle ready fighter.? What's the positive character arc for his over-protective brother?

I, for one, would be more interested in a story naive kid who enlists to fight for a noble cause in spite of the odds, in spite of his over-protective brother.
