Meh. I've seen a few of these pictures -- only on home video, I might add, and never in the theatres, so I really couldn't say anything about how they work up on the silver screen -- and for what it's worth I honestly don't see a lot of distinction between them. Recently, I even rewatched part of the original on pay cable, and it just didn't hold together as well as I suspected it originally had.
I'm a huge supporter of zombie films, so I'll eventually get around to watching all of them (even this final chapter) and maybe even sounding off on them in exclusive reviews for SciFiHistory.Net. Also, I have to admit that the only enduring quality I've noticed is the lovely Milla Jovovich's performance: no, it isn't Oscar-worthy, but in this saga she's proven herself over and over again as a reliable female action star, one definitely deserving of better material. One time, I'd read a commentary wherein the writer called her "the affordable Sigourney Weaver" (in a shout-out to the Aliens franchise and how that particular actress put her stamp on pop culture), and I suspect I'd agree with that sentiment now that her journey has come to its end. (Or has it?!)
As always, thanks for reading ... and live long and prosper!
