Somewhere out there is someone who wants to make an argument that Prometheus is a misunderstood gem, a work of genius that we'll all pretend we loved from the very beginning at some point in the distant future.
I ain't that guy.
Prometheus is, from the point of view of most people (myself included), not a good movie. It doesn't answer any of the questions it sets up, it's needlessly complicated and its characters have less common sense than everyone in Alien: Resurrection combined.
But it's not all bad news. There are, divorced from the film as a whole, moments and elements of Prometheus that are good... when you take them out of the context of the rest of the film.
Some greatness cannot be carried forward. Sadly, neither Idris Elba's nor Charlize Theron's characters can reappear in an Alien movie on account of they real dead. And that's a shame, because all movies are made better with their inclusion.
Here are a few things from Prometheus that can, and hopefully were, carried forward to Alien: Covenant.
