Alien: Covenant - Advent

Seeing as how it's an add-on video, not it's own seperate movie, I feel like you can't expect much. But if you're looking for some answers as to how Covenant could lead to Alien, this provides a satisfying enough of a bridge that if we never get a third prequel to finish off the trilogy, you can still reasonably assume how we finally get to Alien. Again, it's not a visually stunning video, but story wise I feel like it's captivating enough to garner a watch.
