Unfortunately, I find Sci-Fi Dog Lady too impatient with the unfolding of the narrative and her impatience makes her come across as angry.
I see this impatience with allowing a narrative unfold afflicting a lot of non-Trek reactors, as well. They're trying too much to anticipate the narrative and seem to think that not having the answers immediately after they think of a question about the plot is a failure of the narrative. If they'd just wait a couple of seconds, the next sentence or two - the very sentences they're talking over with their questions and objections - frequently answer their very questions and objections.
Too many YouTube reactors just don't seem to know how dramatic storytelling actually works.
