With the "D W" complete body of work being shown on consecutive nights on the cable AMC Channel -- I was able to see the original and this one a couple of evenings apart, both for the first time in several years.
Again, I found myself drawn to a couple of distractions, namely, an unimportant and curious one: Why entitle II and V with Roman Numerals, and 3 and 4 with Arabic ones? Just wondered. Also, couldn't help but ponder from reading Puzo's book and seeing the movies: Who lost more close friends, family, etc., to murder, Don Corleone, or mild-mannered architect/conscientious objector, Paul Kersey?
The original gave a plausible reason for Paul's ability with guns, although he had eschewed them following his gun collector/father's death in a hunting accident.
But as these series installments proceeded, and you look at them anew now, there are other fascinations: Charlie performed these roles beginning in his 50's to a period where he had been eligibile for early social security payments for over a decade.
Further, he rotated between both coasts, having no trouble becoming ensconced comfortably every time, with successful business activity, a host of friends (many of whom met their demise), and a dual schedule which would keep either a full-time businessman or a full-time mob button man busy at his singular profession -- but Paul handled both with little detraction from either by the other.
And his affinity for hand guns (and undoubtedly rifles) as previously explained aside -- Paul also seems to have had the ability to acquire capabilities with regard a wide variety of heavy weaponry and ordnance exceeding a level reached by, say, even General Patton.
Finally, while I've always lived several hundred miles from each coast, my best friend is in L.A., and I have friends in New York City, and have spent regular extended periods in both. In these flicks, unlike any experience my friends (or I) have had, or know of anyone who has -- Paul keeps a dual schedule in both his lives whereby he seems never to be impeded by traffic jams or any big city delays - whether engaged in architectural duties, dispatching hosts of villains, and evading detection just about every time. {He also seems to have the time also (along with the cleverness of a CIA/FBI operative), to infiltrate when and where necessary to further his objectives of vengeance.}
A fascinating "body of work," even more so decades after original release. Among them, though, this one has more intricacy and some essence of plot/some twists/etc., not much evident in the others.
