I liked it a lot. The bumptious politician satire could've been a little less ham-fisted — I already watch the news, we all know what a bloviating megalomaniac looks like (though Ruffalo played it well).
But otherwise this movie really developed and grew from the initial unique concept into something much deeper, touching, and (thankfully) not always so on-the-nose with the underlying message. I'm looking forward to watching again.
