At the end of the last season (or the first of this one?) they were so solemn about the death of 23(?) crewpersons. Now someone dies and Archer doesn't care. That was disgusting.
There's no reason for it. If the writers aren't going to use the full impact of the death, then don't kill him. The writers should have only injured the first victim. Phlox would say that "Another cm to the left and it would have killed him." Then Archer would know the danger and debate if it is worth continuing.
Then, on top of that, the crewperson died because of the deception of the visiting engineer Dr. Erickson, yet no-one even yells at Dr. Erickson. Perhaps it could be resolved with "the damage is done, we now know the risk and how to mitigate it, so we will continue" rather than Archer flying off the handle.
I completely agree with the other reviewers who say that Archer is a horrible captain. He rarely convinces people of things, he mostly uses anger, threats and, of course, rank.
