Near the top of IMDB's top TV shows. I'm about ten years late to this party as I'm conscious that TV series tend to be massive time soaks, which this proved to be. Also I don't want to wait a year to find out what happens.
Coarsely it's an update of The Godfather to the twenty-first century, mashed up with some MacGyverism (and for mine those are the best bits), located in Albuquerque New Mexico (the land of enchantment). It's generally absorbing apart from a few too many saggy family parts and a loss of momentum somewhere in the middle. The finer plot details do not always reward attention. Bonus: Rian Johnson apparently directed three episodes.
The follow-up movie released late last year does not sound as appetising; James Poniewozik reckons the canon was already complete. There's also Better Call Saul.
