BBCA HD claimed that the first episode was being run with "limited commercial interruption" but it felt like there were more than five minutes of commercials.
It did look and sound great. I was glad to get back to having fun with the Doctor instead of the bedside death vigil that were the last few Tennant episodes.
Please! When a companion or even the Doctor leaves, just let them leave! Do not make watching a great show into a kind of wake.
