There's really no way they're gonna get anything other than that reaction. The hype around it, while it has dwindled, always comes back pretty strong every season. They've also fallen into this formula of killing off exactly one (maybe two) characters every season. Not enough to make things feel like they have consequences but enough to pull at heartstrings.
The problem with mystery box type shows like this is that the journey is what's fun, not the destination. The endings always seem to fall flat because they can go one of two ways. They can either provide an explanation that's likely not satisfactory, or they can provide none which just feels really hollow. So by the time it ends you're just like "well that was dumb," but it wasn't about that.
Will I watch it? Yeah, I've enjoyed it so far. I have memories of getting sucked into season 1 so badly that we skipped a day in the park to play Pokemon Go. But I'm emotionally preparing myself for a very lack luster ending. I just hope it's cool, at least.
