To the author, nice work. Kudos.
Wanted to know how it actually works. Are you scrapping at a continuous interval, preparing ui components at those durations and build once it's done.
Adding more content about the show and information about the casts will definitely helps in SEO. Try to add last updated time in all the pages. It triggers google about how relevant data is w.r.t current time. I have done this trick with my blog and it works.
Btw, nice work.
