It would also look awful. The Tennant era wasn't filmed in high-def. We'd end up with something that looks like the classic Doctor Who with some scenes looking video-tapey and some scenes looking sharper on film.Very interesting postulation, that could be quite fun, seeing our current gang lurking in the background and cut into some of those scenes ala "More Troubles with Tribbles"Water is used to put out fires. The forest is presumably a reference to the forest that was used for the books in the library of the dead and wherein the Vashta Nerada laid their eggs. River is presumably River, but if she's the only water, where's Pond? My guess is that Amy rewrites what we've seen in the forest -- saving River from dying physically and so preventing her "data ghost" from having to be uploaded into the data core. Or something.![]()
