The fallen angel has turned out to be disappointed with his life in hellfire. Subsequent to relinquishing his position of royalty and resigning to Los Angeles, Lucifer gets some enjoyment until the point when a murder happens outside of his upscale dance club. Without precedent for billions of years, the murder stirs something new in Lucifer's spirit that is frightfully like empathy and sensitivity.
Lucifer has done itself a lot of favors by selecting a strong lead performer, but Ellis can't carry the show all by himself. The show's writing is too tame to fully embrace all the implications of a main character who is literally the Devil.
Protests have been heard against turning Lucifer into a good guy, but in fact, he's mainly just a smug jerk with a creepy smile. And as his reluctant sidekick, German is as bland as her counterparts on a lot of better shows.
