I gave it a 6. Which, is far higher than I would rate just about any episode from the last couple of years.
Best scene: Archer blows up at Vulcan ambassador (forget his name). Gotta admit, I was cheering Archer on: "Yeah, you tell that pointy-eared hobgoblin!"
Worst scene: Archer apologizes to Vulcan ambassador. Bad Archer, you let me down. But I do understand the need for character "development" and that stuff.
Honourable mention: Trip's scene with T'Pol's mother, where he confesses he loves T'Pol. And then still shows up at the wedding. We'll see what happens next, but that was well done. Talk about being selfless ...
