Until one lives in the city 24/7 one shouldn't judge it.
There are many decent areas in District Nacional and in the outer zones of the city and it can be quite a vibrant place with lots to do despite it's traffic problems and growing pains.
Some comments suggest very limited world travel.
SDO is a growing metropolis in a developing country and no different if not a better major city than in many similar countries with very large tourist industries (Rio, Mexico City, Kingston, Port of Spain, Bangkok, Jakarta, Manila, Mumbai, Dehli, Cairo, Nairobi, Johannesburg, Cape Town to name a very few).
And even somewhere like London, Paris and Milan there are areas just outside the central areas which are almost no go zones.......Miami and other NA cities too.
Why do so many posters continually run down DR. Why live in DR? Why visit DR? Does the country need you when there are so very many and increasing numbers of holidaymakers flying in daily from all parts of the globe into Punta Cana and spending so much more hard currency here?
If your life choice was to put down roots here and it hasn't worked out, have the 'balls' to realize it and move on. If you got hooked with a chica and mistakenly put down roots and regret it, don't cloud the picture for everybody else. If you came here thinking things would be comfy without any formality required to stay and it has changed and are now bitter, don't pass on that bitterness.
DR has a whole lot more to offer than just SDO, Sosua and Boca Chica.........wake up.
