Conclave
If not for man's self-made uncertainties, it is those of God's creations we are united. That belonging limits the abilities of some, for no other man, besides those with uncertainty, would ascend the ranks of self knowledge and through it get to know God.
If there is one thing that makes Conclave so special, it's how it handles certainty as I've described above. Worthy of a watch even if the differences between you and I suggests it isn't.
While it delivers on its two hour runtime, I can't imagine how different, although quality isn't certain, it would be to know each cardinal more- perhaps in a 4 hour film.
