@JGoldman10,
I have to agree. But not just "Black" sitcoms. Most current sitcoms suck.
I have been watching Modern Family which is laugh out loud funny at times, if you take it for what it is. However, I don't think they have any major roles played by Blacks.
On a broader sense, however, I wonder how much is cultural and how much is corporations spending too much time on polls and being cutting edge rather than focusing on substance and quality. Everything seems to be a "gimmick" these days, as they try to push the envelope. Look at Family Guy. I find it horribly wrong on so many levels and yet can't help but laugh until my sides at times. Perhaps it's because I'd like to think that we, as a nation, are finally getting over the uber-sensitivity we're supposed to feel towards all people, animals, plants, and possible alien life forms that haven't been discovered.
PS - Eating Tripe is pretty darn offensive, if you ask me! Nothing personal to our bovine brethren. =P
