We've been a few times. It's a third-world country, with crime, corruption and disease rife. If you stay in your resort, you should be OK. Last time we went (and I do mean it will be the last time), we were hijacked by a group of renegade armed police and soldiers on a remote road in the middle of nowhere on the way back to the airport. Our taxi driver wasn't as concerned as we were, some money changed hands, and we got to the airport. Would we go to DR again? No way!
