I think that's fine. I'm confused enough already. Every time they get close to answers, gee look at that, another mystery under the previous one! One of those Russian doll things. Hope they stick the landing.
if man is 5
then the devil is 6
if the devil is 6
then God is 7
and if God is 7...
That's exactly what was announced - renewed for one more, final, season.
shareThey'll revive it in a few years time.
shareYou definitely want to avoid "lost syndrome", my word for a mystery based series that stretches it out while it remains popular, meaning it has to become bad in order to end, somewhat ruining the whole.
No idea if this is reliable, but this mentions a possible spin off:

I think that is a far better way to go for story based series. The story should finish. Then you can have a spin off which may or may not succeed but won't ruin the original.
Im sure I head somewhere that originally the series was only intended for 2-3 seasons, and only somewhere in the middle did the writers have some inspiration about how to extend it to up to 8.. that worried me at the time.
