Ok having just reviewed Death Wish 1 please see it for commentary on the themes of the Death Wish series of films!
Death Wish 3 is perhaps more of an eighties action film than anything else, sure it follows the same revenge themes, but this time the fighting is on a much grander scale. You have whole neighborhoods and Bikie Gangs involved in really quite big melees. The ante is also upped with bigger and badder military weapons.
Also for the first time the film does not revolve around an incident of sexual violence, this time the hapless victims are a group of elderly people in a city apartment block.
If you enjoyed the series of Death Wish films you will enjoy this chapter immensely.
