Watchmen hot sex scene

What's with all the fuss about the Watchmen movie? I hear many people say it got nice hot scenes well at least they showed the blue wang in the movie. Here in the Philippines, some scenes were cut and some gnarlier ones were not shown. Though I am super curious now and I wanna watch it, I can't decide whether to wait and buy the uncut DVD or to watch it on big screen... @_@
