I respectfully desagree, Lucifer and Michael's storyline is far from over. Despite the Apocalypse being averted in "Swan Song", I firmly believe the two archangels are still destined to have a final battle, ultimately ending with Lucifer's death. Although that is more likely to occur beyond the series' run, that does not mean we have seen the last of them. As far we know, Lucifer and Micheal could return at least briefly by the eventual final season. If so, I have complete faith the writers can devise a new storyline that would be different enough to not repeat the fifth season.
