Well, I'm a fan.
Married with kids. Not in to clubbing, but never was anyway. Nice people, no tax. Get into windsurfing/get a boat. Enough good restaurants to keep you going.
I always apply the perspective: what is the alternative? M25 in the freezing rain/train commuting/ community charge/ASBOS/ tax/more tax/hoodies. I always considered London a great place to visit, but not live. I now hold that view for the UK as a whole.
It's not for everyone, and families and friends are important to some. Bahrain is a 6 hour flight. It used to take me that to get from Yorkshire to London. In this internet age the distance has shrunk - how many people do you know write letters abroad today?
Go for it. And if you don't like it - it's not a life sentence. You just go home again. I miss the tv though.
