I know what you mean about talky face, but depending on the context of the video, it can sometimes be a blessing or a curse. I've never seen an instance of an otherwise perfectly emotional vid where TF has destroyed it, perhaps because in the few instances I'm thinking of, the inability of the characters to effectively communicate has been the point around which the drama builds. (I'm looking at you, Ten/Rose on Bad Wolf Bay.)
However, when the video is of lesser quality, it can distract quite a bit. It makes it seem that the creator wasn't invested in his or her own idea enough to go out and find suitable footage and just made do with whatever was at hand.
I blame the creators of the original source material. Surely it wouldn't kill them to film a silent, soul-searching version of those climactic scenes and put them on as DVD extras? You can't tell me they haven't seen what the fandom does on YouTube...
