What to include
It should only be a summary. Try to avoid describing the episode scene by scene and definitely avoid recreating jokes. The latter rarely works well and nobody wants to have jokes explained. A few paragraphs is the most needed.
How was this episode produced? What were the thoughts of the writers, producers and voice actors? This type of information can typically be found on the Simpsons DVDs. Was there written a special song for the episode or did it include an already known song. Did anything special happen during the broadcasting of the episode? As explained the Simpsons DVD commentaries are the best thing for this, they are the most useful reference available.
Has this episode been reviewed by a notable reviewer or commented somewhere else? Has it been nominated for an award or even won one? If this episode had an impact on popular culture, explain this. Did it make the Entertainment Weekly top 25 list for example? Was there any controversy generated by the episode, whichever country it was?
These should only be mentioned if they are sourced. The section should be written in prose form instead of a list form using bullet points.
These are the key to articles. Any reviews or ratings can be used. And of course the DVD commentaries. This book The Simpsons: A Complete Guide to our Favorite Family and this BBC link will also help. Searches for old newspaper entries and other online sources may also be useful, if such things exist.
