I went for the "They're All Good" approach, because, if I separate out how I feel about the eps in other ways/areas, the TCW stuff comes out about the same, every time.
I'm caught between "Wow, what does it all mean?" and "Yeesh. More time travel paradoxes, reset buttons, etc. So far, it just isn't getting to me: Time Travel is a Trek staple and has produced some of their best eps: City on the Edge of Forever, Yesterday's Enterprise, just not recently.
What makes the TCW different is that it's
1) Not about time travel generally but about a war, some of which we've seen before in limply used storylines (29th century timecops, etc.) but as many have noted in Enterprise: nothing specific enough to take a bite of.
2) For most humans, except perhaps Cochrane, this IS NEW. Even for the Vulcans it appears so new it's not believed. This should be played upon. Archer doesn't know how to convince anyone, T'Pol won't be convinced, Trip could care less, Malcom will believe what he's told, Hoshi will be scared of it, Phlox will be philosophical, and Poor Travis will be unaware. Only once, in Future Tense, do we see how humans handle this very tough concept: Trip and Malcom's discussion about the value of exploration vs. knowing the certain future.
The TCW has great potential, and it has certainly been played up more than the Klingons, the Romulans or the Vulcan-Andorian battles OR the BOTF storyline that was once rumored, but still, it appeared in the first, middle and last of Season One, the first, middle and ?? last ?? of Season Two.
It's there for effect, not for a reason. I want it to be there for a reason.
