I've noticed an alarming trend in television finales, lately: God.
Warning: the following contains spoilers for the endings of Cowboy Bebop, Fullmetal Alchemist, Neon Genesis: Evangelion, Avatar: The Last Airbender, Battlestar Galactica, LOST, Supernatural (current) and The Prisoner.
The presence of God in television finales alarms me for a number of reasons. Culturally, I think it reflects the general shift toward conservatism in the West. Most stories that involve the presence of God (or at least a divine entity of some sort, whether it's Krishna in The Bhagavad-Gita or The Furies/Eumenides in The Oresteia, are about characters finding their path at a moment of confusion, or coming back down to Earth after reaching too high. In both cases, the Divine re-establishes the "natural" order. Arjuna steps into his role as a virtuous prince. Orestes accepts that vengeance is not his to take.
These stories come from an inherently conservative point of view: everyone has a place to stand and a part to play, and attempts to step outside those boundaries can only result in pain and suffering. You'll notice that stories about God commonly involve triumph over the self, not triumph over an oppressive regime - Arjuna never once thinks that he should share his riches with the lower castes, or that he'll unseat the monarchy once he wins the battle. Doing so would overturn the "natural" order of his environment. Arjuna's kingdom, once he wins it, will continue to rely on slavery to sustain itself - because that's how Krishna wants it. God's role in these stories is a conservator, one who might snip off poisoned buds or gently nudge humans in one direction or another in attempt to preserve that which is good and right, without radically altering anything. God conserves the status quo, and we're supposed to take comfort in that: a place for everyone, and everyone in their place.
Recent American television finales have embraced this logic. The endings of Avatar: The Last Airbender, Battlestar Galactica, and LOST all involve a divine figure returning balance to an earthly equation by repeating an ancient pattern. The Avatar achieves his final state and the four nations again live in harmony. Humans create Cylons, battle Cylons, and become Cylons. The Island calls people in need of personal change, gives it to them, then lets them go (to Heaven) before calling another group. All of this has happened before, and will happen again. The pattern doesn't change, it simply repeats.
