It doesn't seem to me like folks are upset with you -- they just feel differently from you! I don't see anyone being angry or upset that you brought up the topic. Sometimes when you make a topic and get replies from 10 different people who don't agree, it can feel like people are unhappy with you -- but that isn't the case! It's important to remember that they're not like, arguing with you or mad at you -- they're expressing a different view in response to the topic!
I think it's way classier to avoid naming names when you run into work you dislike, and it's generally better to describe and talk about the problem than to call out the specific work, so imo you made a good choice there! But I think for any creator on these forums, when starting a topic, it's a good idea to consider if you're curious about others' thoughts and approach, or if you just wanna vent somewhere -- because if you just wanna vent, then it might be frustrating when you inevitably get a mixed response (because creators are a varied bunch). Make sure that's what you actually want!
That said -- honestly, if your general problem with the novels you're describing is "there's a bunch of boring, mediocre work out there," I wouldn't say I disagree? But "there's a bunch of boring, mediocre work" is not a new societal problem... like, there will always be mediocre work. The majority of work will generally be mediocre, as a general rule, and it's okay to not like most of it. It's okay to not like a lot of things that other people like, and to not see what's so great about the things that the majority love. And it's fair to be frustrated when the things you LIKE, the things that make a novel fun and interesting for you, are rare and hard to find.
But whenever you can, I think it can be helpful to try to keep that frustration from turning towards the people making the things you don't care for -- like, instead of focusing on "these novels don't have the elements I enjoy, they're a chore to read, why do people like them???" -- it's okay to feel that way! But I try to focus instead on "these novels really don't do it for me because I tend to prefer novels that have X, Y, and Z!! I want to see more of X because it's my jam!! It's so hard to find Y and I want to see more stories with it!!!" It's the same feeling, but a more positive expression of it that's easier to reach out with and find likeminded folks!
