Spoiler right there is Episode 1, thanks
During the 'coming attractions', as the crew strides purposefully toward the camera, they are one member short. Way to give it away, folks.
MAGA!
Somewhat worse than that (to me anyway), they showed in the opening couple minutes the crew trudging through the Martian night with an injured crew member. Hmmm... think something's going go wrong with the landing? Maybe when the get in the rover it's not going to make it all the way? Oh, surprise! lol.
The dramatic end of this just isn't working for me so far.
