I think they have underestimated how many of those puffs would end up on screen... I think that while shooting, the director must have thought you'd only see them sporadically when the final cut is done, but it winds up looking a bit silly now, like something out of the Armageddon attraction at Walt Disney Studios.
Then again, the makers of this show have proven in the past that they prefer spectacle over credibility -- see how they represent turbolift shafts as some gigantic industrial thrill ride existing in a pocket dimension bigger than the whole damn ship.
I mean, it's not like they would've had to wait for the final cut to see how it looked. With digital video, they could have instant playback of any shot, and I'm sure the practice of watching rough cuts/dailies as they go is still around. If it had been a mistake, they would've noticed it in time to go back and reshoot. But they've done it two weeks in a row now.
Increasingly, I take solace in Gene Roddenberry's point of view that
Star Trek is not a literal documentary of the events it depicts, but a dramatic recreation after (or before) the fact, with its imperfections and inconsistencies being attributable to budgetary and technological limitations, artistic license, or adaptational error.
Is it really such a big deal? Not for me. I've enjoyed these first two episodes tremendously nonetheless!
So have I, but it's still an annoying distraction in the middle of something I enjoy, like ants at a picnic. It doesn't ruin the experience, but the experience would be better without it.
