These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
One-Scene Wonder: Steve Buscemi as the Beatnik bartender who's increasingly exasperated by a drunk Norville's inability to comprehend that he's not getting a martini in that establishment.
