The font of all wisdom?

Thanks to primewire.mx, I've been able to watch series I've never managed to see before (e.g. Sherlock, Dirk Gently's Holistic Detective Agency [the US version]) or to finish series I had already started (e.g. Lucifer).

I have to say that Lucifer and Sherlock have had some great advice - especially when it comes to family relationships and fathers in particular. I sometimes wonder if they have 'therapy advisors' to read through the scripts or whether the scriptwriters have themselves been in therapy for many years and are just repeating what their therapists have told them. 

Whatever the case may be, having good advice come at you through an entertaining and gripping story line is a very palatable way of obtaining it.

In a sense, such US crime series often put me in mind of 19th and 18th century literature. In such books, you also hear the sensible thoughts of the author, which also have useful nuggets of advice in them. Who'd have that Anthony Trollope and the scriptwriters of Lucifer had anything in common?
