Prometheus

I think this serves as a pretty decent stand alone sci fi. I like quite a lot about this movie. The cast is good. Noomi Rapace in particular is very good.

I like the idea of the engineers, I like the idea of the black goo, I mostly like the idea that this all spawns the xenomorphs we know and love but I don't really understand why.

Not everything needs an origin story and I preferred Alien when we just thought they were out there somewhere. I don't think we needed an origin/backstory/genesis story.

Take out the final scenes which, if I'm honest, felt a little forced, and Prometheus would still have been a fairly decent sci fi.

And most notably, Prometheus does teach us not to run in a straight line.
