What the hell is wrong with you yanks? DIVING BOARDS a LIABILITY?? cripes, here in Canada we still have Diving Towers.

Forget 3 - 4 feet off the water, I know of two places within driving distance of my place where you can dive off a platform 20 feet above the water.

While the violence in Watchmen probably exceeds the brutality of that seen is Sin City, the difference is that is has a "message". Its a comment about our protagonist, about them being human, and nothing more that costumed vidulaties, many with severe physiological issues. Far from the costumed "Heroes" they originally strived to be.

The Major difference: the Violence in Sin City was designed to be "enjoyed", while the violence in Watchmen is intended to disturb.

To be fair there is (as mentioned somewhere above) a big difference between disipline and abuse.
