TATV could have been a good episode, even a good series finale, with a decent but ruthless rewrite. It seemed to be written for insertion earlier in the series, like S2, with Trip's death tagged on. None of the characters were in line with how we knew they had grown from S3 on. So their reactions and decisions seemed like regressions. For example, by now Archer knows how incredibly important the first steps of the Federation are: he's seen the future and the ramifications if it doesn't happen. No way he deviates from that course for a rescue mission. Trip (aka Space McGuyver) knows that Archer always at least tries to escape - and they know each other well enough to practically read each others' minds (way back in Andorian Incident, they communicate with sign language, mirrors, and eyebrows). No way Trip resorts to a desperation move without trying to come up with a plan with Archer. Reed? MIA. There's no Reed Alert (which we know happens automatically) and no MACO response. And, as others have pointed out, there's no affection or sadness at Trip's death from Reed (who, arguably has become Trip's close friend), or Hoshi (who spent her "last minutes" with him once). The six year time gap adds name tags (which I actually like) but no promotions.
Someone other than B&B should have taken the script and conformed it to the growth and development of the characters as they were at the end of S4 - and then developed them further to account for the six additional years. Give Trip an actual reason to sacrifice himself (JiNX's idea is really on the money).
Review, revise, rewrite. I have no problem with Archer's speech not being shown; it leaves a real sense of walking into the future.
