I like Futurama, but I don't think the Simpson's is going downhill. There have been some really bad episodes, but the Simpson's is still breaking new ground. Behind the Laughter was hilarious, as was that duffman episode ("Duffman... Can't Breathe"
. The Family guy is ok, the baby is great, but the dad is too stupid. I know that its a cartoon and isn't supposed to be believable, but come on some of the stuff is not only incredibly stupid, its not funny. The PJs has some good Ghetto humor, but its not going to last. As for X-Files, the plot was incredbily f*cked in the begining of the season, but it got back to its roots later on.
