Muli Ne really that Bad?

Dear community-members, as I am going to the south of Vietnam for the first time (have been to the north a few years before), I chose Mui Ne for a vacation of about 10 days. I just wanted to enjoy the beach, browse a little through Mui Ne, hop to Phantom Thiet and try to feel the Spirit of Vietnam. Enjoy the countra, try to get in contct with the people, Taste Ban Mi, Pho or other dishes. Was chosing Mui Ne the wrong decision? People are writing really bad about this town. I did not recognize this in Germany. The Reputation of Mui Ne is much better here. What is your oppinion? Is Mui Ne ok for a Vietnam-starter? Thanks a lot!
