Probably Cloud Atlas
It was a commercial failure so it's usually one that people haven't already seen.
Talented cast and directors passionate about the project.
It's extremely divisive, most people either love it or think it was a waste of time.
¯\_(ツ)_/¯
Don't think I've seen Foundation or Silo mentioned yet.
Maybe sense8? Much like the expanse it takes a while to get going
