R Rated version on video

Jesus, don't rent this movie on video. It's a super sweet movie, but they cut out nearly 15 minutes of footage, from what i gather. Plus they cut out all the cool ultra-violence the nc-17 version or the unrated version have. Just not nearly as cool. I'm quite dissapointed.

*spoiler*
Also, the end is really strange. I don't know if the uncut version ends the same way, can someone help me out? He is on the boat and kills Jadot or whoever, the bad guy with the sister. He tears out his throat, off screen of course, then stands up, but he's shot in the legs, so he stumbles around a little. That's it. He falls into the arms of the girl and the guy he's supposed to fight next. Is that how the regular version ends, or diid they cut out the entire last fight?
