The over dramatization of the various narrators are SO overly dramatic it completely overrides what they are trying to tell us. It's aggravating. You do not need your hands or your extreme (fake) excitement to get your point across. It literally takes away from the show itself. While watching the show, your eyes do not track their faces, but instead sees only the hands or the fake excitement. Most disturbing when trying to watch the show. There are a few shows that apparently do this same thing, and their directors actually promote this kind of thing with their narrators or guests. Please stop them. Allow the viewer to take in the information or theories being presented without all the extras that provide nothing.
