Being a Bloodrayne Fanatic, knowing just about all there is to know about her, the game, and its universe, I've know about this movie for the better part of six months. And each day I've been dreading it. They screwed up so much about the franchise, I won't even bother making a list.
The plot won't be expanded on, because the movie is a 'prequel'. Taking place back in the 1300s; which, if I remember correctly, was WAY BEFORE Rayne was born.
So, I'll go see it, just for the love I have for the character, but I doubt I'll enjoy it. You may want to keep your eyes open for my nice, ugly review.
