Pretty impressive

I was half expecting it to be a StarWarsy episode with the flying into the weapon, destroying it, and then Daniels saving Archer at the last minute and telling him to work out a treaty if possible.
What was done instead, was much more interesting for where the story was obviously heading.
The Enterprise getting torn apart was awesome, until of course the little bodies flew out of some of the breaches...

It's going to be interesting to see how they get out of this situation. Somehow I think though that the NX-01 is no longer spaceworthy and the NX-02 is going to be designated Enterprise and Archer will get command of it.
I did like the J mixing the D and E design, but in my opinion I think it looked too low-tech for the period it was supposed to be in. (I'd expect the ship design philosiphy to change in the 200 years since TNG/DS9/VOY. A ship closer to the timeship that they had in the earlier Enterprise episode when the Tholians attacked.) If anything that would have been a good F or G design.
Of course, my main question is how do the "evil shadowy figures" who are bossing the Pseulobon(sp?) as well as the Tholians relate to the war with the Builders.
