If i could solve all the political problems by killing a few people... it would have been done. (probably by someone else)

Meaningless killings really turns me off.
Not to say i haven't laughed a few (such as the steam roller incident in Austin Powers)
Nor to say lots of killings put me off (such as Ronin. Lots of murders, lots of setups, but we know why, and that is the driving point of the story)
