I must admit there was one bit in Kobayshi Maru where I thought Archer's characterization was way off:
When the distress call goes up from the ECS Kobayashi Maru, and a bunch of shifty things are going on all at once, Archer thinks "What the fuck?" to himself. I don't bat an eyelid at swearing, but it just seemed totally wrong for Archer (who didn't swear under torture, when torturing others or when killing unarmed civilians), utterly gratuitous, quite childishly executed and stupid. If they were gonna say "fuck" in Trek for the first time ever, it would have been a much better fit for the Trip/T'Pol reunion in the shuttle
