Mario Puzo has given the world many novels and scripts becoming the basis for fine movies, e.g. The Godfather trilogy. As for The Sicilian, the screenwriters made it a dubious historical action movie, with an odd choice for the leading role - Christopher "The Highlander" Lambert who obviously lacked the features characteristic to e.g. Robert DeNiro or Al Pacino. The result is a kind of Italian Zorro or Viva Zapata!, with beautiful but difficult-to-remember women; luckily, there are some fine supporting performances, particularly John Turturro as Gaspare "Aspanu" Pisciotta and Joss Ackland as Don Masino Croce, and real Italian atmosphere. But the 2+ hours was too much, there were many scenes not providing additional value, and some lines-links could have been totally avoided. But first of all, one could have a real choice whether to make an adventure movie or mafia movie.
Thus, unless you have decided to see everything connected to Puzo or Lambert, or Turturro, skip The Sicilian.
