I&#x27;m really sorry you didn&#x27;t enjoy the Martian but they specifically introduced his character to be like that to the point the other astronauts talk about his personality.<p>Don&#x27;t forget that he was on his own with a big delay in communication. So from a science perspective, he&#x27;s talking to himself so why would he be formal checklist guy, and from a movie perspective they have switched the inner monologue of the character to be an external one into a &#x27;video diary&#x27; to make the story watchable. It&#x27;s a story telling device.<p>While there are movies deserving of ire the Martian isn&#x27;t one of them and definitely not for the yelling and screaming.
