I think it depends on what you expect really. My family have lived in our hamlet for 7 generations but my wife is an incomer although she has become somewhat naturalised after marrying me.
The bad (based on things DW moans about occasionally - having being brought up a city girl):
Shops far away so you have to keep a good stock of food in.
You can get cut off in snow in the winter
Going out to restaurant / cinema / theatre requires MAJOR planning - either staying over or expensive taxi home.
Shopping trips are the same - it's a full day out to go anywhere with any decent shops (apparently).
You end up being a taxi service to your kids until they can drive - then you just worry about them driving on dangerous rural roads!
Farmers (like me) and their tractors clogging up the roads making you late for work, plus my animals can smell (sorry but if you live here you have to put up with it - this is the back of beyond, not Kensington).
The good:
Very few people!
Fresh air
Beautiful views
Endless places to walk your dog (just keep to the countryside code)
No traffic
No noise
Sooooo peaceful..... I don't even take holidays very often. Don't need em!
If you are truly serious about moving to the country then you will love it, but only if you integrate. It's no good moving to the country and then complaining about the noise of the sheep, or the odd tractor cutting the hedges when you're trying to do the school run.
What the countryside does not need are people who work in town buying up all the nice houses then using their home as some sort of dormitory as their work / social life continues to revolve around their city jobs / lifestyles. People who do this rarely have a good time of it.
If you do move to the country try to become a country person - rather than a person who happens to live in the country. Integrate into your new community and you will love it.
