I think they might go with an iTunes model where you can buy one series at a time.

I’m spitballing here, so don’t expect a perfect solution, but I think it could work like this. You get to watch the first episode of say “Severance” for free, then can opt to buy the next episode for $1.00 or the whole season for $5.00.

A favorite movie would be $5.00 for five viewings, or unlimited viewings for $20.00

See?
