"An article or section of an article that relies on primary source should (1) only make descriptive claims the accuracy of which is easily verifiable by any reasonable adult without specialist knowledge, and (2) make no analytic, synthetic, interpretive, explanatory, or evaluative claims."
So it looks to me like a straight synopsis of the events depicted in a TV episode easily fits that bill and is not considered original research.
I somewhat agree, but take a look at a Family Guy episode summary.. any one. See the Cultural References section? All facts listed there are entirely OR!
From "Peter's Got Woods":
"When Shauna, Brian's love interest introduces herself, there's heavenly singing of the name 'Shauna' in the background. This parodies a scene from Ferris Beuller's Day Off when Jennifer Grey's character tells Charlie Sheen's character 'It's Jean, but most guys call me Shauna.'" -No source, based entirely on editor's personal knowledge! THese things are all over these summaries!
