I'm really sorry you didn't enjoy the Martian but they specifically introduced his character to be like that to the point the other astronauts talk about his personality. Don't forget that he was on his own with a big delay in communication. So from a science perspective, he'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 'video diary' to make the story watchable. It's a story telling device. While there are movies deserving of ire the Martian isn't one of them and definitely not for the yelling and screaming.
