I don't know why people have hangups over crying to be honest, but it's your opinion and that's fair. My opinion is that considering how the crew has lost literally everything they ever knew, there realistically should be more crying. This out of universe "crying is bad" is exactly the same thing that causes Detmer to break down in-universe, and people in real life, because everyone's expected to act macho all the time in reality and, apparently, in fiction.
I guess it just hits a nerve with me because people (not anyone here, in general) say "Oh, they should have been honest about their feelings etc. instead of killing themselves, turning to drugs/crime, etc." and then the moment someone does cry and open up they are treated as "wimps", "God helps those who help themselves", etc.
If the crying bothers people so much, they don't have to watch Discovery and can send their money straight to rivals Witcher and Mandalorian on Netflix and Disney Plus, where everyone acts macho all the time no matter the circumstances. No judgement if you quit the show, I myself quit Lower Decks after Episode 5 and only stay on CBS for Picard and Discovery.
I don't have a problem with crying or showing emotion. I'm a highly-emotional man.
What I have a problem is that the writing often relies on melodrama rather than earning their emotional moments... tears or otherwise. Like Airam's funeral. How can I grieve with the crew when the show did nothing to make me as the viewer care about Airam?
The show uses crying as a means to gain audience sympathy without doing the work to earn that moment for either the characters or the audience.
