When it comes to scripted shows it all boils down to personal taste. I love Family Guy, Simpsons, Futurama and Aqua Teen Hunger Force for instance. They all make me laugh and have a good time, so it's all good.
But when it comes to reality shows... they are all evil, unless they actually contribute in any way to the world. The worst of them all is a crap show called Fashion Jury or something. They parade this poor sob before a "jury" who say that the person is ugly, without self esteem etc, then proceed to "fix" the person. They usually turn a person with a lot of personality (cool frizzy hair for instance) and turn them into a generic everyman. Seriously, in every episode they cut, straighten and stripe the hair. They give them fake ceramic teeth (dunno what it's called) even if their teeth look fine, and they usually do some cosmetic surgery to "fix" their face. Seriously, it makes me angry.
Oh, and every soap-opera out there. I want meaningful drama, not this drivel.
