Agreed, the crew is awful. I thought I'll catch up on it during my sick leave over this week, but so far...I ended up rewatching best episodes from previous ST shows instead, I just can't bring myself to watch it. The best characters in show, by far, were passing characters. Pike get only little to do, Burnham is one-dimensional Mary Sue with acting more wooden than entire man o'war, Tilly gets to be more annoying than Neelix at times...
Plot of S2 is rehash of the old "evil AI" trope done to death. They don't even bother to think of a reason for it...even the worst cases of evil AI syndrome in TOS had some reasoning behind it. This time, it's simply taken as automatic that computer that achieves sentience becomes omnicidal. And they try to propel it with shock value, rather than clever writing, while they don't actually have the possibility to be sanguinary like GRRM...so it ends up being pathetic instead. The only permadeath so far was a stupid, supposed-to-be-heroic-sacrifice of the worst kind, with incredibly rushed buildup-the character was essentially rushed from background what-the-hell-this-android-looking-thing into something we're supposed to be sympathetic with within a span of two or so episodes.
