What annoys me on these reviews is that they seem to be completely ignoring one of Season 2's best episodes, Cogenitor. But they love bringing up Carbon Creek, which was really just an average episode. Cogenitor was the kind of storyline they needed to do more of on Enterprise while Carbon Creek was business as usual.
I have always been baffled by this. From when it first aired this episode never got the recognition it deserved. To me Congenitor is Enterprise's best episode by far. There is nothing else like it unless you start looking at the top morality plays from some of the other shows.
