Drakmar, its not just warriors...everyone has a guardian star that goes out when they die.
However, it would not mesh at all if they showed a star going out for Vicious. The last scene and the song and ending sequence are an honor for Spike. Vicious was an evil bastard, so it doesn't fit that that sad, sad ending would honor him.
That said, I'm glad the movie is coming to America, though the R rating annoys me. I'm not too upset though, since, IMO, the movie was not as good as the series.
