It's actually a pretty good scene (just watched it, thanks)... I think Troi's line is the only thing that gives it an unfortunately staged "Star Trek 101' feel to the affair. But what do you do; she's there, you have to give her 'something' to say. I'd love to get a Meyer/Bennett MST3K-style commentary on her line though. "Really? We weren't required to know any of that stuff when we made our movies"... "That's because you chased Gene out of your office, you soulless bastard!"... "I did, didn't I?"
I suppose one could argue this story is the foundation of Trek mythology, and Cochrane is the 'visionary' stand-in for Roddenberry (for those who insist on calling him that) who meets these people and immediately 'gets it' as to what they're about... hence his coming up with the same term Roddenberry did when pitching his series. (Just don't tell Moore and Braga; they might take credit for it)
