Even worse was Eric's collection of Star Wars toys. This is in 1978 and he somehow has a Yoda and Palpatine figure. Was Eric a time traveler? Did he break into George Lucas' mansion and steal them not knowing what they were?
It kind of sucks, because Eric's entire Star Wars dream sequence is clearly from the perspective of someone who's only seen the first movie. A love triangle between Luke, Leia, and Darth Vader is not something anyone would imagine after Empire Strikes Back unless they had an incest fetish.
So you can tell they at least tried, but fell short with some small oversights. Ultimately forgivable, but still needs to be nitpicked.
