I think it’s just the beginning. They’ll split seasons eventually into 3 or more parts. Or if you wait till all seasons are released, they’ll paywall earlier parts. They know people won’t wait that long, especially with how easy it is to have things spoiled by social media or among friends/co-workers.
That’s a real concern if you’re at all worried about spoilers. It’s so easy just to have shit spoiled even if you try to avoid it. Passively hearing about it from school/workmates, social media, or even radio. The stupid radio spoiled the ending of Breaking Bad for me and I never got over it, I guess.
