The truth hurts
Uh, many who visit the DR do feel this way, and it seems that people either love it or hate it, but amongst the Americans I know that have visited the DR (granted, mostly they visit Punta Cana or Playa Dorada), most hate it and will never go back, despite my best efforts to convince them to the contrary.
It seems the more well traveled a person is, the more likely they will hate it, the less traveled, the more they will like it (mostly from ignorance about the rest of the wonderful places in the world).
In my experience:
#1 reason for people loving it? The people! (read: the ladies like the Dominican men, the men like the Dominican ladies).
#1 reason for people hating it? Quality of everything sucks.
There are many many places in the world where the dollar goes a LOT farther than the Dominican Republic, just not in the Caribbean.
