I always stop and watch when that trailer comes on. the moment after she stops swimming like a dolphin is the most I resume my normal breathing.

Cool. I suspected as much.

One detail/connection I noticed that I thought was nice/weird was the use of glowing white for blood, and then the admission by Bishop(?) Roark that Kenny was filled with "White light" when he fed.

I wonder if that was coincidental style choice or an intentional connection. I'm leaning towards intentional. either way it's pretty cool.
Definitely my favorite RR film by a loooong shot.

It was intentional as this is how Frank Miller illustrates it in his comics. Robert Rodriguez nearly went panel for panel from the comic for the movie. Frank Miller is a comic creatin' demi-god.
