Agreed 100% about Smash Lab.
Mythbusters used to be great, but in the past season or two it has become nothing more than obnoxious. Adam continues to try to be a showman, but he's just so annoying and he rarely gets things right. The so called 'build team' lack any and all chemistry on screen; if they would stop trying to play to the camera and just discuss the myths they're doing like normal people maybe they'd be tollerable. Jamie is the only part of the show that is still worth watching for as he's the only one that ever seems to know what he's doing and doesn't try to play to the camera. On top of all that, they don't really test the myths properly anymore; I realize they don't exactly have a budget to do things perfectly, but they cut so many corners at this point that they aren't testing the myth anymore.
Now for my list:
Lost, CSI and its clones, The Riches, Law and Order and its clones, The Shield, reality shows especially American Idol, the new American Gladiators, Lil Bush, Weeds, Family Guy, American Dad
I'm sure there are more, but I can't think of anything else at the moment.
