SERIES PREMIERE: This is a warning, not a recommendation. This new Syfy series is an inept, inexplicable continuation of the little-seen movie Legion, which dramatized an earthbound battle between angels, involving humans as pawns or prey or precious beings to be protected. The movie was nothing special, but this TV continuation, set 25 years later mostly in a reconfigured Las Vegas called Vega, is a lot worse than that. So skip it. Every time a viewer tunes in to Dominion, an angel loses his wings.
