I’ve seen posts (I wish I could find them) talking about how literary critics read way too much into literary works, finding meaning where the author meant nothing more than what he/she actually says. I found this about the movie “Pulp Fiction” and thought it was a perfect example of that in the film world.
“There was great speculation about why Marsellus Wallace had a band aid on the back of his head. People who give Tarantino way too much credit theorized it had to do with Wallace’s soul being in the briefcase, since the devil takes your soul from your neck. As if Tarantino thought that deeply. In reality, Ving Rhames cut himself shaving and Tarantino thought it looked cool.”
