It seems like you're only seeing the aesthetic side of design and missing the functional side. For example interface patterns, typography and color palettes can be evaluated without opinion.

Interface patterns have their best use cases and the designer needs to pick the right one for each part of the design, making sure it works as a whole.

Typography is based on making text easily readable - there's always some leeway for opinionated typography but a designer shouldn't stray far from best practices.

While the exact colors in a palette can be opinionated, they too have characteristics that should be assessed without opinion. Are there enough contrast between the colours? What if the user is colorblind? Will people with low vision be able to see everything clearly, especially text? Are the colors appropriate for their intended use, for example a red hue for alert, green for success)?

"It does not look right" and "it does not work" are the kind of feedback you get from people who don't know the inner logics of a design. Feedback from an experienced designer might not mention aesthetics at all.
