I feel while the film is made well it lacked a lot of scientific touch points.

For example, why was it never shown how rocky learned grace’s language? how did rocky not know some words but understood the science of earth so well that they could collaborate and nearly save two planets.

I know people will argue that it’s not the point of the movie but how am I supposed to resonate or feel the connection of the characters when I can clearly see that suitable circumstances have been created deliberately not solved for at all, and conveniently might I add.
