It was not my favorite Trek episode, but it was all right. A lot better than any of the episodes with time travel, but then, most anything would be.
I liked that both Trip and Archer, during the argument, had valid points of view. I agreed with Trip's vehement, injured reaction at losing a crewman because of the scientist's BS story, but I also sympathized with Archer's idea that, since they were there, it was their duty to try and save the kid.
Whether or not Archer was letting his personal history with Emory affect his judgement was too close to call, in my opinion. It was probably the best 'talkie' episode since 'Cogenitor' (which I loved).
