Classic example of censorship making things worse *MAJOR SPOILERS*
As staunch fans of the film know, the US 'R' rated version - which was apparently sold internationally - considerably dilutes Kate's elevator murder.
In the uncut version, the 'coup de grace' is shown. As the climax to some generally more explicit slashing and dicing, 'Bobby' finally slashes Kate's neck arteries, which will obviously result in a fairly swift demise no matter how quickly the medics could arrive on the scene.
In its truncated form however, this particular shot is eliminated along with several others; as a result of which, the supposedly 'toned down' sequence just comes across as a bit of showy slashing with a bucket of blood having been sloppily sloshed around.
For me, all that achieves is to remove that realistic edge of 'painful' murder from what has ensued. Since we don't see the actual injury that makes Kate plausbily die, it feels like a more 'superficially enjoyable' screen spectacle because it is a bit bloody; rather than being a gruelling, harrowing sequence depicting the prolonged actuality involved in getting a human body to die - which is far more soberingly horrific.
