I like the death scene in Videodrome where this guy is being turned inside-out after being shot by James Woods

Another death I truly like was the death of the sadistic
Rhodes where they teared him apart.I really enjoyed
watching this:
Another scenes I liked was in Alien with the chestburster that
teared John Hurts stomach apart(I found this to be intense)
and the scene in Alien:Resurrection where one of the aliens
slit the metencephalon of some guy.
