Unpopular means not liked by many people. An unpopular decision, unpopular at school, deeply unpopular.
It counts rather than judges: an unpopular decision may be the right one, and saying so is the standard defence of any hard choice. Unpopular opinion is now a set phrase used to introduce a view the speaker expects to be argued with. Note popularity, unpopularity; and that popular comes from the Latin for the people.
