I have to say that when the ending came, I was very pleasantly surprised! If you like all things NASA related, and a more slower, intellectual movie, I think you would like this movie.
Like a lot of people here said, it was moving pretty slowly, if you are expecting a Marvel or Cloverdale type movie, forget it. But if you enjoyed movies like The Man from Earth, this is the movie for you.
I say to the entire team, Very Well Done!!
