Does it just end with no explanation - with many loose ends, leaving the watcher to 'make their own ending'?
I hate that. it's starting to feel that way.
If so - I will stop now.
No. I watched it and nothing interesting happens at all. Its boring and they had material for 2 episodes maximum. So its like 1.5 movie that is stretched for 6 hours.
It does reveal the main plot but still leaves some things murky. It's worth it. Why don't you see for yourself instead of relying on people who might be just trolls. It's just a few episodes.
It doesn't end "open-ended" so much as "begging for a season 2 that Amazon has promised won't happen."
For "open ended" I'd point to "Cast Away," "Inception" or Frank R. Stockton's classic short story, "The Lady, or the Tiger?"
This series took a lot of time to set up critical plot threads that it not only failed to resolve, but ended right at the point of huge next steps, as yet untaken.
That's not an open-ended ending. That's a cliffhanger. And it'll never be resolved.
I would recommend against this one for that reason alone
