The Ending (SPOILERS)
I already posted this on another thread, but I thought I might as well talk about the ending as its own post here.
I think the ending was fine. What didn't work well was the choice of Norman Greenbaum during the end credits. Probably one of the darkest endings as of 2017 I've seen in a while, and then Spirit in the Sky comes on in the end credits. Also, I think it would've worked better if was edited differently to impact the ending harder. In fact, the dark ending should have gone further.
Say the ending focused on Jake Gyllenhaal's pod as one scene, and then cut to Rebecca Ferguson's. Just have the movie's end focusing on her hurdling into deep space, no music in the background, just her screaming and the controls going awry, then cut to outside the pod where we can't hear her scream (because in space no one can hear you scream), and watch as the pod drifts further, and further until you can't see it anymore, and then...Directed by Daniel Espinosa. No Spirit in the Sky, no music. Just pure silence as the credits play over the shot in space, and maybe as the credits continue to roll, the camera pans over to earth, and we see lights from all around the world begin to go off. Maybe its like an accelerated montage were HUGE fires break out, maybe a several HUNDRED explosions, and it just ends with the total destruction of Earth.
