This is a quick mention for the US version, as per the above link. It has a different front cover.
All of the series 7 episodes are included as well as "The doctor, the widow and the wardrobe" Christmas special, as per the UK version. The only difference is that the CBBC "school winner" short video "Good as Gold" is not included. This short video features the Doctor and Amy with an appearance by a weeping angel. Instead, on the US Edition there are some interviews with Matt Smith and Jenna-Louise Coleman which were shown on the US series "The Nerdist" (this is shown on BBC America). It's a chat-show format and Matt appears via satellite while Jenna is on a video recorded PODcast. Both interviews are informative and Matt gives some interesting insights into his take on The Doctor. As these interviews run to 15mins and the Good as Gold short is 3mins I know which I prefer!
The series itself, as others have stated, is a mixed bag and it is subjective as to which stories are better. What is undisputed is that this series has garnered even more US fans, as can be seen in the footage of the filming in New York and at the San Diego comic-con convention. Plus the fact that there are New York buses with adverts on them for Doctor Who means that the series has well and truly penetrated the US market! Long may it be so!
