Dominion seems to be the successor to the 2010 film "Legion".
For those that don't remember it the plot is as follows, God abandons the Angels and they decide its mankind's fault, and thus the apocalypse is born. One angel alone amongst his brethren sides with humanity, and comes to a remote diner to protect one expecting mother whose child is prophesized to be mankind's only hope of survival.
Dominion is set a significant while after the invasion, where by all accounts the demonic (angelic) invasion wiped out all but a few walled off highly defensible cities holding the last of human kind (the one we see bares a strong resemblance to Fallout's New Vegas), and then became somewhat dormant.
The show has believable sets and effects, some interesting stylistic choices on armor and swords and city architecture. The plot isn't incredibly unique, but its not derivative enough that you will know the seasons plot after one episode. Although you likely will guess whats happening throughout the episode 30 seconds before it does happen, nothing is all that surprising.
Decent fight scenes, acting that's up to par, multiple sources of adversity from the Angelic threat to your own people, with one particularly self deluded villain that you will instantly not like. They highlight some social issues like caste systems and economic disparities, which might become important to the story later down the road.
Everything about the pilot is promising, if you're into fantasy entertainment this probably will excite you. Word of caution, only the pilot is released, and its from the Syfy network which doesn't bring its A game often (ever?). The only recently decent show from Syfy was Helix, which started out equally powerfully with no overt mistakes and a promising premise, but the more episodes of it you saw the more obvious it was that the possibilities you imagined in response to all the mysteries the show introduced were vastly superior to the illogical garbled mess the story turned into by the end of the season. I enjoyed the pilot, but if you're short on time wait for a while to see if the show maintains its quality.
