During the period of writing of this updated review, both brothers happen to be Searching demons, devils and all way of preternatural beasties for a strong Supernatural tv show---a near eternity in television terms. Because in this CW world, devils will always lurk behind every bush, more worlds and ruin constantly be looking to corrupt more souls and only make everything a living hell that is literal.
And Sam and Dean (using every last touch of the knowledge they gleaned from modeling school) occasionally have to give these almighty beings a bit of a talking to. You know, to straighten out their precedence. Not that Sam and Dean are themselves with problems of morality or peacefulness. Their language is scarcely ever kept by them in check, plus they occasionally one or the other of them gets right into a scenario that is sexual. Blood spatters like rain in Seattle. Heads roll like bowling balls on the PBA tour. While the show is self aware and campy enough to make all of the blood feel a bit less ... bloody, it's still there, in greater amounts than you'd see in a shocking old Hammer horror movie.
