I've reloaded my save and re-run the same TV show multiple times, with slight variations on the card.
The overall show grade keeps rating 5-10 points below what I would expect, based on both the individual segment ratings and what the past few similar cards received.
Any thoughts on what the reason would be? The only thing I can think of is that I only have two storylines graded as "hot" when I'm required to have three. I know that can result in penalties, but I didn't think it would be quite that drastic...
