I am just trolling
hope this is allowed. Because if I post real examples as you encouraged, it will become troublesome and would rather talk it in private.
To answer the question seriously it is hard for me to entirely hate or be repulsed by an art style. There are of course art style which is uglier than others in my eyes, but let us not ruffle some feather and even lowering my
near zero approvall rating.
I also do think same face syndrome is not that affected with art style; it's just either the artist preference (wanting all characters look "attractive" with preferred features, and ended up with six handsome boys that aren't meant to be sextuplets), incompetence (not knowing to integrate certain features in their style), or laziness. However, because it is important for storytelling and character recognition (plus the boredom it caused for the audience) I understand why it is a problem.
One thing my pet peeve are styles that are copied or inbred form of popular art style, which the flood of its trend cause repulsion.
For example look at popular art styles like one of popular artists' (e.g. Meyoco or SakimiChan) or franchise (JoJo's Bizzare Adventure, Steven Universe). I have no problem with any of their art style although I tend to dislike or like some more than the others. When their styles boom and become hyped, many people are copying it for various intentions (admiration, experiment, clout, or narrow visual library). The trend creates flood of similar-looking art gracing my feed, they look all the fucking same, and I grow to dislike it so much and wish that shit would stop appearing before my eyes.
I also feel a bit disdainful for people whose existence is just copying popular-artist-of-the-season's art style, or being overfixated with a certain art style that they only draw in it. While copying art style is a good form of study and useful in the industry; making a copied style your identity does not help. It breaks my heart when beginner (I am a beginner too) artist feel disappointed because they can't copy their art idol's style and feel they're inadequate.
