Sorry for not writing for such a long time - my first try got erased before I sent it, but I'm back now to answer your question! It was the writing. I found so many of the dialogues to be really cringeworthy. To be fair, this was not the case for all the episodes. I felt ashamed to bare witness to some of the dialogue in The Sound of Thunder for example, while Light and Shadows was ok for me. I truly suffered through the Red Angel arch. There were so many things that just didn't make any sense to me that I kind of stopped caring. And there was so much unending declamation with no real depth - all I saw were actors trying hard to say the flat lines as well as they could. I continued watching Discovery even after this season mainly because there were great characters again, that is Discovery's strength in my eyes. And the later seasons seemed better to me. Have a nice day!

That does make sone sense, yeah. I'm confused, because Saru is otherwise depicted as very empathetic, it's even pointed out verbally, but this situation was different and it came so early on that it was hard for me to believe his empathy for a while afterwards, so I'm not very sure what the writers wanted me to think.
