Can we reprogram Korean TV?

Seriously, what is it about death and crimes on korean tv? not one sitcom over here, but almost every CSI/NCIS/Criminal Minds/etc at night on the English channels. And that does not include some bad action movies that i end up watching. True, we are supposed to have super fast cable, or i should download things on iTunes, but laziness wins out, and i end up watching some bad shows. and it really doesn't help a good night's sleep when half of them involve murders. you would think i might learn ;)
