The antonyms for the word "more well-received" are less popular, unpopular, rejected, disapproved, and disliked. If something is less well-received, it means that it is not being welcomed, appreciated, or admired as much as it ought to be. Something that is unpopular is not liked by many people, whereas something is rejected when it has been dismissed and disregarded for not meeting the expected standards. Similarly, disapproved means that something is disregarded and frowned upon by the majority of people, and disliked means that it fails to gain anyone's favor or appreciation. Therefore, it is crucial to consider the opposite of well-received while expressing one's opinions or describing something.
