Actually, I've just found out that is meant to be a prequel (source:

You didn't pay much attention in the others did you? Wasn't it the first that gave us 'flashbacks' of this very scenario which they're exploring in further detail here in 3? (When I first saw the preview of this one I didn't even have sound, but I immediately recognised where it fit into the sceme with the other two - maybe I've watched them both a few times too often, 'eh?)
Of course there's no Kate / Selene, she hasn't been introduced to the story yet let alone turned in this timeline. Personally, while I love her character, I found myself increasingly sympathetic to Lucius' plight in these movies. While it's in my inherant nature to sypmathise generally speaking with the bad guys (so long as they're flawed enough to seem 'realistic' and not typecast as ignorant ******* that can't shoot for **** and have no sense of humour) in this series, especially the first, at the end, when Lucius was urging Selene to bite Michael, all you saw behind his actions was love - a love he suffered for all his life, as opposed to the stringent laws and restrictions of the Vampires' way of life.
It's dark, it's visual, it's emotionally grounded with action and supernatural themes and usually has a complimentary kickass soundtrack; What's not to love about that?
I can't wait to see it.
