Now that I’ve thought about it some more, it’s unlikely the movies would be making any decisions based off of what’s best for the streaming shows. That would probably be seen as the tail wagging the dog.
That said, I’ve definitely encountered people who enjoyed the films but skipped the shows on account of not knowing where to start and finding the relationship too confusing. It would make sense to pair a successful “early days” movie with an “early days” spinoff series to lure some of that casual audience to streaming.
