Ahh, yes! -Another take on the vampire lore! I like the fact that the writer of this thing is trying to do something different with the vampire idea (as others have tried to do). The basic change always seems to involve removing some of the traditional qualities of the vampire that most of us are familiar with. In this instance, the writer went for broke and removed almost everything but the need for blood.
I'm none too happy with that.
The vampires in Night Junkies seem like ordinary junkies or ordinary people with a chemical addiction. There is nothing eerie or supernatural in their appearance. FOR GODSAKE, THEY DON'T EVEN HAVE FANGS! IMAGINE THAT! Practically speaking, having extended incisors makes taking blood more efficient; "neater" in fact, since you need only make 2 puncture holes in the right place. However, with regular "human" teeth it becomes a messier affair as it requires some tearing of flesh to get what you want. We could therefore say that these particular vampires are not as evolved as traditional vampires with there long sharp "practical" fangs.
I think the main reason for these untraditional vampires is that the writer (and most of the IMDb commentators) wants a fresh perspective and to "update" the vampire idea. I'm all for a fresh look at the vampire idea but I really believe you do a disservice to it when you take away the eeriness and creepiness of it; the "supernatural" or "otherworldly" flavor of it, if you will. This is a big part of what scares you. So why take it out by stripping the vampire of so much of their power? The vampires in this movie are horrific only in the sense that serial killers are. Nothing preternatural about them, just psycho. This is one reason I did not like the movie that much. But also, with these human-like vampires, the movie seemed more like a depressing slice of life of those who live on the fringes of society due to mental disorders, drug addiction, and prostitution. Everybody in this movie seemed depressingly dysfunctional. In fact this "vampire" movie comes off as a METAPHOR for drug addiction and the sad lives of those so addicted. So if you want to see this movie -BE WARNED! It is a drug addiction-type movie more than a "vampire" one.
I guess some writers feel that the vampire idea is more believable (and more interesting) if they are more human than they traditionally are. There may be some truth to this. But I say there has to be a way that the traditional vampire who is able to become a bat, a wolf, smoke, and able to climb sheer walls and hypnotize the hell out of you could still be interesting to today's more sophisticated audience.
