I think that the original Death Wish was a very powerful and relevant film. As for the sequels, hey, they're for Bronson addicts, period. Part II was exploitation pure and simple, Part III was ridiculous and highly enjoyable, Part IV was going through the motions, and Part V...? Well, let's just say that Paul Kersey is back. Period.
Yeah, he's still an architect. But he's just THAT close to taking up his night job, which is vigilante extraordinaire. By now, he's a very seasoned pro. So when some mobsters whack out his girlfriend, he's goes on the offesive and starts doing the cops' work without the whole civil rights problem, etc.
Bronson's revenge is swift and violent. He poisons a canolli, he blows up a soccer ball in someone's face, he kills. Period.
Is the film any good? Naturally, no. This is low budget. Heck, even the film stock looks crusty. But it's a Death Wish sequel, and even fans won't expect more than the usual. Paul Kersey tries to live a normal life, but gosh-darn-it, he winds up being the vigilante, yet again. Someone's gotta do it.
This is not the best Death Wish sequel. That honor may be taken by III. But it's watchable. It's Bronson. Nuff said.
