I've been across the pond and have seen the shows which are not rebroadcast over here. Trust me, what we get is absolutely the cream of the crop from the UK. Most of the stuff they create is horrible, much worse than anything you'll see on any major network in the US, and often worse than the stuff TLC or Lifetime show here.
If we could take just the best 6 shows from the US and use them to define how great US entertainment is, everyone would be very impressed.
That said, An Idiot Abroad is terribly funny.
