I am from the USA (Southern part) and have never heard of Dr.Who, I thought he was a James Bond character or something. However, taking this in account, I believe this set would be a hit in the UK, but a flop elsewhere.
Glad to see I'm not the only one in disgust of the waste of space for the manual instructions. Good modification, I myself managed to add four cannons on my Brickbeard's bounty by adding another midsection.
