^^ Please don't tell me what I'm thinking or not thinking. I'm actually considering it from all of those angles. Sure, to film it in HD, they may have to change the construction. Big deal. As long as it is very similar to the original, with more detail showing, I don't see the problem. Or, maybe there's an in story reason for it looking low budget. After all, the TARDIS scrounges for its parts, apparently. So, who knows where it got the parts for the original console room?
Although, I would guess that if it were used in Doctor Who, they might replace the photo blowup wall with a real wall. Or, did they do that even for the documentary, can't remember if we can tell from the photos or not.
