I've watched about 90 seconds of each episode, in 10 - 15 second snippets randomly in the episode, and have concluded:
she uses too many of what she probably thinks are dramatic pauses (or she loses her train of thought)
a rehersal prior to recording might help, along with the use of an outline and/or notes
the lighting is terrible
she needs to get a new shirt, something other than that same old black one
she needs to stop saying "you know" - if "we know", why is she wasting our time and hers telling us.
