I just had a glance at the analysis of The Big Chill since Melanie mentioned it in her Secrets of the Quad video. Its storyform in the analysis section is off [as in incorrect].
All four throughlines have Universe as Class.
It's the same bug as the "Being John Malkovich" analysis. The analysis part has some of them; for example, a few movies won't appear when you use the Analysis Filter (Zootopia, The Princess Bride).
