This is the fourth of the five 'Dirty Harry' films, made 12 years after the original, and the only one directed by Clint himself. It also stars Sondra Locke who was Clint's long-term partner...
By 1983 the 'Dirty' Harry Callahan franchise was looking increasingly old fashioned, not only because Clint was now 53 but also the series had lost its freshness and novelty. Harry Callahan is referred to in the film as a 'dinosaur' and this is not far from the truth, not only because of his policing methods (blast all baddies with a .44 magnum) but also a shortage of ideas and believable plot lines. Here, a woman serial killer is on a revenge rampage, shooting her victims first in the nether regions, then in the head. Clint single handedly (of course) tracks her down with (of course) no help from the local cops and (of course) metes out his own form of summary justice to the remaining baddies and his own idea of justice to the killer.
This isn't the worst of the 'Dirty Harry' films (that's reserved for the last one) but it really is very average stuff. 3/5 stars.
