This is a tough one to rate. Basically gave it an extra point for making the attempt. I get people not taking to it but their reasoning is odd to me. Being an Australian movie some people just ain't gonna like it. Just the vibe and whatnot.
The music. Yup, that's an issue indeed. Being musically inclined myself I think I figured out the problem. Sort of. The score itself isn't bad, and seems like the right instruments are being used and played appropriately. If I had to to name the main issue I suppose it's that it sounds like they couldn't afford better. Just produced badly, the EQ is way too biased to the high range, and comes off grating. Then they mixed it in too loud. Kinda like a big Hollywood movie how the strings will blast you w/some patriotic thing like a laugh-track telling you when you're supposed to feel something. Though in this case I'm not sure they got the feeling they were hoping for. Often distracting and at best can be tuned out.
There are several good things though. The "main" vampire character that you follow in the beginning is great, I thought. He's got a unique appearance that works really well later on. Kinda like the old Salem's Lot (cool vampire, not-so-cool movie). Old-school creepy. Has character and I really watched it for him.
There's not a ton of hardcore vampire violence or big action sequences. To me that was fine. Didn't feel like they made it work because they couldn't afford to or something (maybe that's where the soundtrack budget went, or someone owed a relative a favor there). I thought it all came together quite well.
There's a core group of characters and though I found some irritating, it was okay for the most part. There was some dialogue introducing a couple of them that was fairly painful to listen to early on, but you might have one hand on the mute button cuz of the soundtrack anyway so no biggie.
I feel you could watch this movie w/out really thinking too much and it would be adequate. But there's more there if you bother to notice. There's none of that vampire romance stuff. Tom Cruise's pseudo- homosexual Lestat wouldn't fare well in this particular universe. I'm usually pretty lenient w/any movie that tries something new. For instance, I practically loathe Vin Diesel but I'm okay w/Pitch Black being around even if I don't like it (Cole Hauser doesn't do his movies any favors in my book either come to think of it) if only for using a true sci-fi premise. Maybe not the best one, but I couldn't match it to any movies I'd seen in the previous decade or two. Same thing w/the Caretaker. The true meaning of the title isn't kept secret necessarily, but it develops more impact and depth as the movie goes on. Someone gave some thought not only to the vampire genre but also a plausible idea for how humans adapt to all sorts of stuff we really shouldn't have to.
There are some sour notes throughout. Some character motivations are more complicated than they would first seem, but some are just dead ends so you end up getting annoyed at times. Overall though, I'd say watch it. Just keep in mind, these people have some issues. Many of which would need some serious therapy to dig out. One character's actions, more than others, can be... confusing. Just stick it out, I doubt you'll regret it. Am I going to watch this again any time soon? No, pretty sure I won't, but I know I will again. If you're a vampire fan though, you should watch. They went for creepy and disturbing (as the whole vampirism concept really is) without spoiling it by laying out all the "rules" and negating the mystique. The focus isn't on visual horror, more the inner torture that most of the characters are submitted to.
I imagine becoming a vampire would kinda blow personally. You wouldn't think so from most of the movies you see though. Nowadays you trade mortality, soul and a tan for eternal life, orgasms just from eating, permanent make over and a new black leather wardrobe. The vampires in this movie's world are tortured beings that aren't wild hunters so much as hosts for a hunger that destroys them. Without the doctor they wouldn't have been able gotten that across well but he sells it. Just wish I had a subtitle track for some of the dialogue. Sound editor can just go ahead and go deaf though, might even help.
