I usually watch the episodes as they air from the BBC feeds using the TARDIS method of acquiring shows or repeats (for me) on the ABC in Australia which is also commercial free. However when watching reruns of NuWho on cable (UKTV channel) which has commercials they always seem to break at the weirdest moments and it sometimes disrupts the flow of the show. Is it shown with or without commercials in the US?
With, as it's on SyFy, isn't it ?
My point was that a typical episode of Doctor Who will lack obvious places to put advertising breaks. There won't be any scenes where a Dalek is just about to fire and then it fades to black before coming back with the Dalek just about to fire again.
I'm aware of all that, but it's always been my understanding that even most BBC drama programs tend to fall into something close to the one-hour drama format that's the television standards in the U.S. And even then, the idea of a single, normal episode -- not a two-parter, and not a special, and not a made-for-TV movie -- taking up an hour and a fifteen minutes just seems absurd to me.
While it is increasingly common for the BBC to produce shows with international sales in mind, there is no absolute need to do this. In addition, many BBC shows fill the full hour.
If a story takes 75 minutes to tell, what's the problem ? The alternative is to pad it out to 90 minutes and make it a two parter to the detriment of the story.
