You should check out the movie reversal of fortune. It follows a homeless dude that was given 100k no strings attached. He was specially chosen as he did not have any substance abuse issues. Despite that the story has a sad ending but it does humanize the struggle as you grow to like and empathize with the guy while the slow rolling train wreck carries on
