Fantastic.
More than once I thought to myself, Man, this feels like The Godfather.
High praise indeed.
Granted, it's not THAT good, or THAT saga-like, but it has that powerful x-factor that draws you in, conveys a sense of heft, grit, gravitas and importance, and never lets go.
I learned a lot, and was entertained all the way through.
Strongly recommend.
