Movie Script Analyis Analyzing Themes of Evil in Phil 1666

Experiment #2 Plot Arch Analysis

After getting a general feel for the average sentiment of each film through the word cloud visualizations, I wanted to see how the sentiment changes over the duration of the film. The following line graph represent the change in sentement from start to finish. I have highlighted important turning points in the commentary on the right to add more context to the charts.
Sentiment analysis requires a high amount of computing power and takes a long time to run. This particiular graph took around 45 minutes to generate. Due to lack of computing power and time I could only perform this analysis on one movie. I chose The Exorcist, because I wanted to see how positive and negative sentiment changed as Reagan became more evil.

The Exorcist


The film begins on a positive note as we are introduced to Chris and Reagan. Darker themes soon come out when Reagan finds the old game box in the basement and begins to mention Howdy. Good sentiment spikes soon after during the party and other scenes of relief. Soon negative sentiment comes back on top as Reagan begins to become possessed. At the end of the film, we see the large separation of good and bad sentiment. This is when Fr. Karras faces off against Pazuzu and then ultimately dies. Reagan becomes freed from the demon and the movie ends on a final spike of positivity.
