A scene from Final Destination 3

Lewis' Death:
This is when Lewis dies in an unaxpected way, when we see the knives come down we (the audience)think he is going to die or his arms are going to cut off. however the knives cut the ropes off the weights that Lewis is using; then we see something really unexpected happen the weights come and CRUSH his face and blood splatters out. This meets the generic convention of a thriller, because something happens that the viewers dont expect and there is blood.
