I forgot to mention...
The 2003 remake of The Texas Chainsaw Massacre.
WORST. MOVIE. EVER.
(I probably could make a whole WORST. MOVIES. EVER. list, but at this particular moment, this is the one for me.)
When confronted with Your Friend Hanging On a Hook Who Pleads With You to Kill Him (and you know that there's no way he'll live even if you're able to get him off the hook and away from Leatherface and if you kill him at least he'll go quick instead of, you know, an excruciating and drawn out death on a hook), what would you do with the knife? Slit his throat, which yeah, I admit is gross and horrid -- but quick -- or would you STAB HIM IN THE STOMACH?
I just... wow. SO LAME.
