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.
For what it's worth I did not ignore Cogenitor in my review. It's a great try by the Trek writers to address both general concepts of gender and the concept that a person can be considered second-class status because of a social construct.
