Finally got to see the episode...
The theme song definitely has to go. The original one had started to grow on me, but this faster more upbeat tempo just doen't do it for me at all. As another poster has stated, it is extremely at odds with the direction that the show is going.
I thought it was a decent episode and I hope this represents what the avergae episode will be this season. The "Archer-taken-hostage" angle is getting way to thin to be much interesting anymore (if it ever was). I do like the idea behind the Xindi, with several species evolving on a single planet and not all of them humanoid. It's about time Star Trek aliens started looking more alien.
The addition of the marines is welcome and their interaction with the rest of the crew should be interesting as the season goes on. Malcolm's headbutting with the Major may provide some much needed (if not interesting) character development. We'll see where it goes.
The T'Pol/Tripp scene was gratuitous, but not as bad as I was expecting. I think the relationship between these two characters has a ton of potential (not romantically or anything like that) if handled right. But then again so does the show if it is handled right. Personally I find Tripp to be the most interesting character on the show, next to the doctor - everyone else seems way to bland. Except for Travis - he's more of a bridge prop than a character anyways.
The debris field that may or may not be the Xindi homeworld will need further explaining. It's too early to tell what the debris field really means, we'll have to wait to see how the season plays out. Is there more to the story? Is it bad/lazy writing? Who knows...
Bottom line for me is that it was not a waste of my time watching this episode, which is more than I can say for more than a few past episodes. It was entertaining if not fantastic. If I use JC's rating system I would also give it a 2.5 out of 5.
YMMV with this show considerably.
