Terra Prime was a good close to the series. It felt like good Trek, some drama, some action, it generally made sense (the array was reasonably explained, I presume it doesn't work against shields or there was some other perfectly good reason why it wasn't used on the Xindi weapon), and I'll presume that part of Mars was pointed toward that part of Earth at the right time for that shot to work. Hoshi actually taking command was nice touch to it all as well, as was Malcolm going back to his Section 31 contact and seeing them again. That felt like the real conclusion of Enterprise. If it had ended there, at least there was some vague sense of completion: although damaged the diplomatic underpinnings that would lead to the Federation had been built.
These are the Voyages was two things, a footnote-glimpse of the day the Federation was founded, and an appendix to the TNG episode "The Pegasus". I can see how the cast of Enterprise felt like second-fiddle at their own finale, being shunted to being holodeck characters just there to be background to a story told a decade ago. You could tell Manny Coto was out of the loop on that one I'm sad to say. Trip's death belongs right behind Tasha Yar on the Senseless Trek Deaths list, with Kirk getting randomly shot in the back also way up there (of course, Generations and Kirk's death was another Berman/Braga concept, so this is par for the course for them).
