All Pope's have made their mark; some for good, some not so good. People make the mistake of judging the Catholic Church as a political, peer-pressured group. No popular vote is needed to follow Church doctrine.
The Church is a family. Pope does not mean king or president. It means father. How can you compare how one father teaches their children to another father? (Considering they're both upright people.) The Pope does not need to uplift the Church's reputation; only teach It's members how to be good Catholics in an otherwise challenging world.
And with his life Francis has already given witness on how to be a good Catholic and relate well with other people.
