[...] "Demons"/"Terra Prime" could quite easily have served as an incredibly fitting conclusion to Enterprise that emphasised why humanity needs to reach out to the stars with open arms, in the spirit of co-operation.
[...] I think I'll finish at "Terra Prime" and leave on a high note.
Your certainly not the first person to make that observation, many fans (myself included) and one of the people who ran the show (I forget...was it Mike Sussman, or Manny Coto?) consider "Demons" and "Terra Prime" as the true finale of Enterprise, partially stemming from the sort of comments you made, and the fact that TATV...well...sucks. I have not watched TATV since it's first airing (or once or twice after that possibly) and that has been it.
