It's broken. My sentiment of La La Land was nowhere near that cheerful lol. In all serious though, its pretty cool idea for data analytics.

#32I'm always a little wary of the robustness of sentiment analysis; in my experience, if you take the time to check sentiment analysis results sentence by sentence, you will find a high error rate.
I haven't confirmed by looking at the source, but my suspicion is that either most sentiment analysis implementations are rule based or are not well tuned.
My go-to example is IBM Watson's sentiment analysis service rating "I hope you die" as very positive because the sentence is categorized as "hopeful". Which I suppose it is, technically, and perhaps this is a case where I'm expecting too much because recognizing this particular example as having a negative sentiment requires much human abstract reasoning and inference, but the example remains nonetheless because real-world language usage that isn't dry and technical is rife with these sorts of linguistic usages.

#33Interesting project, horrible presentation. The colour gradient on the graph is confusing - does green mean happy, blue unhappy, and the movie changes tone over time? Axes of the graph are not labeled, what are we looking at? But, those concerns are secondary. Bar graph seems a poor choice here, given the nature of the data. Given that there doesn't seem to be any correlation with time, the order of phrases doesn't s…
You're right about the graphs. The horizontal axis is the minutes of the movie though (on the second graph). Will get rid of the gradient and add labels!
I love the visualization! Is the website a template? What lib for the graphs?
