This year's line-up of documentary short Oscar finalists is a heavy bunch. Three deal with terminal diseases, one touches on post-traumatic stress, another focuses on the heart-wrenching fallout of natural disaster and social policy and still another observes the psychological rigors of a particularly gruesome occupation. Only one of the films fully eschews troubling stories of struggle. Perhaps that's less a commentary on the films themselves than the world they're documenting.

In any case, it's a rich assortment. And it will really come down, in a few cases, to what "type" of film voters want to pass on through to the next stage. Because — and not to be too reductive — there are a few instances of similar turf being trodden, though never with diminishing returns or impact. Each of the movies is expertly rendered and tells a vital real-world story. No surprise, then, that they've made it this far.

So once again I've taken a deep dive into all the finalists. Much like with the animated shorts, I'm happy I'm not the one who has to whittle it down from here, but I imagine all viewers of the lot will return to their regular lives a little more enlightened. Learn more about this year's contenders below, with accompanying trailers where available.
