In an effort to save time, I'm going to just paste the synopsis of Live Evil provided from IMDB.  Apparently it's taken from a press release, but it still gives a detailed description of the film, so I'm using it here.

A hunter dressed in black. This cowboy-hat-wearing samurai-sword-wielding Priest is on a quest for blood. Vampire blood. He's out for revenge on a "clique" of four vampires who are traveling across country in search of "pure blood." The human blood stream has become polluted by drugs, alcohol, Aids, Diabetes, anti-depressants, cigarettes, anything that changes the blood even a small amount makes it undrinkable for Vampires, who, like hi-performance automobiles need "hi test" fuel= Blood in order to survive. This has started a sort of underground civil war between various groups of vampires and vampires themselves have mutated due to the pollution of their life blood. Live Evil is what is written on playing cards left behind on the bodies of dead vampires that this mysterious Priest/Hunter leaves in his wake as he gets closer and closer to our main group of vampires. He's out for revenge and the real reason for this is not revealed until the very end. He's as cold blooded or more than the vampire he seeks, because he has to be. The Leader of the group of Vampires is Benedict, the "oldest' of the group he's seen the rise and fall of the vampires and is out to protect his small family of vampires. He's also in love with one of the two females in his group, Sydney. Sydney is a sexy but equally ravenous vampire who is becoming more and more out of control. Yael is the youngest of the group and the most enthusiastic and inexperienced, of these vampires; her recklessness could threaten their group's existence. Also part of the group is the acerbic Baxter, an Irish former silent movie star, who became a vampire in order to stay young forever only to have his career ruined when sound films came in. His bitterness and Yael's young enthusiasm create more tension for Benedict to try to control. This clique is constantly trying to find pure bloods for food and also on the run from The Priest who gets closer and closer to them with every mile as they travel to Los Angeles to find a Blood Dealer, Max, a man who "pushes" blood stolen from hospitals to vampire clients. In a wild opening sequence car chase the Priest's car flips over and his right leg is injured so severely that he must hijack a ride from Roxy. A tough woman who doesn't know if the Priest is just insane or if there really are vampires. As the two grudging companions get to know each other The Priest learns that Roxy is a "pure blood" and realizes that he must do more than just seek revenge, he must not care for another human being for the first time in his life. Neither Vampires, nor Vampire Hunter Priest take prisoners in this increasingly frenzied cat and mouse game. It's a bloody trail of bodies, both human and vampires, that climaxes in an abandoned church in the barren desert.

After seeing how long that description is, you can see why I chose to copy it rather than typing all that out myself.

So now that you know what it's about, let me tell how how it actually was.  Basically, to sum it up in a few words, if I didn't know this film was released in 2009, I'd swear I was watching a vampire flick from the early to mid 80's.  Why?  Because that's exactly what it looks and feels like.  The general story, the dialogue, the acting, the visuals...all of it screams early 80's vampire flick.  That's not a bad thing really, I was just surprised by it because that's not what I was expecting.  Honestly I tend to prefer those older vampire flicks because the ones that started coming out in the 90's really sissified the whole genre, and basically ruined it in my opinion, so it's nice to see someone going old school and bringing back some of the action.  Yeah I know Tarrantino did it too, and there have been a few others trying to make vampires cool again, but once a genre is ruined, it takes a variety of really creative films to bring it back to life.  This happened to the zombie genre too a while back.  Zombie movies were a dime a dozen and they were all the same, but once people realized the genre was dying, they started getting creative with their zombies.  Films like Junk, Dance of the Dead and many others started really going all out with their zombies and really helped to change people's perception of the genre, which finally brought it back to life and made it interesting again.

Anyway, back to this film.  While I liked the creativity of the vampires struggling to find pure blood in a population that had been corrupted by pollution, substance abuse and disease, as well as the fact that a variety of different types of vampires existed in the film, including night only vampires, day/night vampires, vampires with a mouth in the palm of their hand and even baby vampires, there was something lacking in this film that even the great Tim Thomerson (who played the vampire hunting priest) couldn't fix.  I just didn't care about any of the characters.  They were all literally cardboard cutouts and very two dimensional.  Tim Thomerson's character was about the only fun one in the film, and even some of his dialogue and stuff he did felt rather contrived at times.

Ken Foree makes a limited appearance in the film too as a vampire who hosts "vampire parties" and sells pure blood like a pusher sells drugs.  He helps out the main clique of four vampires in the later part of the film by giving them some blood and his car.  It didn't help much though, because at that point it was kind of the beginning of the end for them.

Technically the film is well made.  There's some nice fights, some good gore effects and it all just generally looks like a well produced film from the early 80's as I said before.  The sound and lighting are both good, but I can't speak to the visual quality because the screener copy I received had really crappy visual quality in a lot of the scenes, normally I wouldn't have accepted a screener of this quality to review, but it was already sent before I found out, so I can't really comment on the full on quality of the upcoming actual release.

Screener quality aside, that doesn't change my opinion of the movie, which is this.  Live Evil is a somewhat fun, somewhat entertaining and rather creative vampire flick that'd be a good Sunday afternoon watcher.  I say that because it doesn't really have the terror or suspense to make it something you'd need to watch at night to get the full effect of, but if you check it out on a lazy Sunday afternoon, you'll probably enjoy it.  It's not a bad movie by any means and would probably be enjoyed by pretty much any horror fan.  It just doesn't have much in it to get really excited about other than seeing Tim Thomerson "kicking ass for the lord!" one more time.
