I have not seen the film with the same name, so I have no opportunity to compare, but the Series captivated me from the 1st episode. Wonderful and apparently realistic atmosphere (with real events and real persons included), skillful mix of comedy and tragedy, great performances (Francesco Scianna as Massimo and Edoardo Buscetta as Salvatore Giammarresi excelling others a bit)... And pleasantly and surprisingly free family relations in a Catholic country, with reference to love and growing pains. With 2 generations constantly visible, it should be both interesting to parents and children, with apparent explanation what was going on in Sicily in the late 70ies / early 80ies.
Although the Season 2 is somewhat less interesting / more protracted than Season 1, yet 9 points from me, well done! And again, as after watching Montalbano series, I am very keen on visiting Sicily, still never been there.
