I feel that "Lucifer" jumped the shark at that moment and (shockingly) bereft of ideas, chose to introduce a cynical and unrelatable reactionary religious angle into what had been until then an imaginative, charming, witty, clever, suspenseful and romantic series. However it all went to Hell -pun (sadly) intended in the final moments when Chloe "found" religion and was revealed to be in thrall of some evil priest. Many of the characters that we had come to know reappeared and it looked like there was new promise of an approaching rapprochement among the various parties - and hopefully a new level of intimacy between Lucifer and Chloe.
Series four, episode one started off very promisingly with Lucifer pining for Chloe as the camera did some "fancy footwork" with the changing background behind his piano. Loved the concept, the characters, the situations. I was a big fan of the first three seasons.
