The most surprising thing about Seth MacFarlane's Family Guy: Something, Something, Something Dark Side is that they had such a dearth of black characters (pre-Cleveland Show) to work with that they had to use "Mort Goldman" in brownface as Lando Calrissian. For those who don't follow the show or find themselves sucked into syndicated airings periodically (like me), that makes no sense whatsoever.
Family Guy's Empire Strikes Back spoof, like the New Hope one before it, relies as much on the framework of the original films as it does in-jokes from the Family Guy universe. I found it much more digestible than most FG episodes, so I suppose the solution to stomaching MacFarlane's work is to chase or blend it with something else.
The Blu-ray includes a commentary with MacFarlane, Seth Green, three producers, and the director of the 54-minute "deluxe episode". They touch on why they'll never do a spoof of the prequel trilogy and various bits that were cut or re-written. The "Fact-Ups" (pop-up trivia) are as informative as they are satirical of themselves. My favorite featurette by far was the one that covered the hand-painted cover art they did called The Dark Side of Poster Art. It's about ten minutes of graphic design geek fodder. The full table read of Something, Something, Something Dark Side is included, as are the opening minutes of the one for the next chapter.
