The only one that really springs to mind, rage-wise, is Lost. I lasted two seasons and got sick of the show presenting more questions than it answered week after week. I did come back just for the finale to find out what the whole mess was supposedly about, and what a cop-out! The first 2 seasons of Happy Days were the good ones, they actually put some effort in to create a half-decent period look. After that you get overt 1970s hair and clothing in 1958 Milwaukee. And the Fonz, originally a James Dean-type character who only spoke a word or two 'cause he was too cool to bother with the squares, became a parody in season three.
