In addition to the two credited directors, I suspect that there was a third one used for a particular scene. George Romero must have had a few suggestions for the two bloodiest minutes (it seems longer) in the history of adult cinema. We are "treated" to a close-up of the separation/operation of Sabre and Racquel that is guaranteed to make you toss your cookies. This is unfortunate because these repulsive moments detract from the rest of the video, which is pretty well done.
Of particular merit are the Cara Lott-Tianna-Tom Byron threesome and the group scene at the end. Really very little plot development —the girls decide to be parted and in what someone must have thought was a hoot, get sliced apart in a scene for which forward scan buttons were invented. The sex is nice, but let's leave out the gore please.
