Whatever it is, I hope they have it planned. Having no explanation will eventually drag the thing down.
So far most of the clues of what happened seem to be targeted towards a religious conclusion, something that would probably be popular with broadcast TV viewers. It will probably play a bit less well with streamers, but I think it will still hold up.
Anyway, the explanation is why I'm watching. The rest hasn't been that compelling for me to say I need to see it play out week by week.
As I've said in other threads, I'm enjoying it just enough to keep going and look forward to the next episode. I fear that it's going to lose me at any minute, but hopeful that it will actually turn out to be a good show.
The explanation is either going to be spiritual or scientific. Personally, I hope for spiritual. There have been too many movies and shows lately about parallel universes and wormholes and time travel for the explanation to feel fresh at all if that's the direction it goes in. Something more otherworldly could be fun, though.
It's also going to be interesting to see how the shadow person plays into all this.
I'd love it if they really went super religious. I'm sure the title of the show is a clue. Manifest is one of them words with lots of meanings and writers like to be clever.
I have some pretty serious doubts about them going too far into the religious side of things. 30 years ago it would've made sense, as the broadcast networks didn't mind mentioning religion and actually seemed concerned about offending the religious elements of the population by being negative on the subject.
These days it seems like all that's been flipped on its head. Now everyone is shy about portraying religion is any kind of positive way and they're much more worried about offending the secular folk in society.
So we'll see how it goes. But if they do go "super religious," as you term it, it will actually feel like a breath of fresh air to me just because everyone in the entertainment industry these days seems reluctant to touch the subject unless they're either tearing it down or tip-toeing around it with vague and generic mentions of a "higher power" and nothing more.
I don't care what they come up with. I just don't want it to get all apocalyptic and these passengers have to try and save the world. Which is almost certainly going to happen.
The story can be how it affects their lives. Unfortunately there are rarely good explanations for these mysteries and bad explanations drag the show down.
I dunno, I can tell you that for me my interest always dips when it goes to the more mundane stuff about everyone's relationships and all the crime solving stuff, and then spikes again when we return to the central mystery of the story.
I'm not sure how they're going to draw this out over multiple seasons though.
