My boyfriend watched Lucifer and I would occasionally watch in with him. I found the lead character a bit unrealistic in an immature way. I.e. someone that old would have gotten past some of the deliberately 13-year-old things they put in there to appeal to the young-adult market. But of course it's a story and wants to interest the target market with fun sex and swearing and stuff.
In any case, the show is now cancelled. What do you think? should they have done a 'wrap up' episode just in case of this, like Castle did? (Castle - another show with an immature hero for a similar reason. And in that case, an actor who was selfish and immature as a person, too.)
