Yeah, I mean that's fine. Clearly your no fan of the game (or not a big fan, at least), and that's all good but I just simply disagree with pretty much everything you've said about it
I don't agree that's ND are stupid, or it's Walking Dead levels of writing, or it makes no sense, etc. I find all that very hyperbolic, personally. It's the same as when people said it was Game of Thrones season 8 bad. Come on. It's just so over the top and almost performative. What you find poorly written or characters not being consistent, I just don't agree with that. Most of the things you seemingly have a problem with, I never have done. I think the vast majority of it (apart from one or two things) makes sense and IS consistent.
As for the bold part, not sure what's not to get. I admitted that HOW she went about it was quite psychopathic and over the top, but that's the frame of mind she was in, I guess. I can see that turning people off, though. But I don't agree that she did it with a sense of gratification. Granted, she probably went into it for that, but she certainly didn't get gratification during or after, I don't think. I'll give another shout-out to the game here for not lingering on it, either. I didn't find that bit gratuitous at all.
As for empathizing with her, we're just coming at it from a different point of view, I guess. As I said in my previous comment, empathizing with her or finding her redeemable/irredeemable, etc., wasn't the point for me. As long as characters are consistent and interesting, and I can understand where they are coming from - even if I don't agree with them - that's all I want. And I think ND did a good job on all that (again, apart from one or two moments). If she DID slit Dina's throat, then for me that would be a step too far and I don't think that would have been consistent with her, to be honest.
I don't think the game is flawless or anything. There are problems with it, but I will always give it credit for ambition and having the balls to do some of the stuff they did (god knows the AAA game industry needs it), and for the most part, I think they did a great job.
