This cracks me up because this is where I have to admit I was actually re-watching some bits of BloodRayne last night (strictly for fanfic research purposes :p). It is really amazing to see how completely off absolutely everybody is in that movie. How can people make a movie and look so unconvinced the whole time?
Don't get me wrong Kris, even slightly befuddled, still looks adorable, and Michelle looks yummy as usual despite the ridiculous fake accent and the silly lines. But why didn't they hire a choreographer for the fight scenes? Clearly Kris was on her own with the choreography for most of her fight scenes and you can totally tell.
If I had the time I would rewrite the whole thing with Michelle in the friendly freedom fighter role. Unfortunately I wouldn't be entertained long enough to finish it.
