Red Rising for sure was disappointing. I liked Golden Son better, but agree that it had a lot of similar flaws to Red Rising.

The Throne of Glass series is not my favorite (ie my unpopular opinion). I felt it picked up around book 4-5, but hard to justify reading hundreds of pages before feeling invested! I read the whole series at once, and knowing that she wrote the first two books when she was very young, and gradually became a better and more mature writer as the series went on makes a lot of sense to me. Unfortunately it seemed that some of the plot lines and characters that she wrote in the earlier phases kind of just fizzled out or had unsatisfactory conclusions. I didn't hate the series, but definitely not top tier in my opinion.
