Mythologize? Me? Captain Debunk? Mr. "Source, please"? To quote Bugs Bunny, "He don't know me vewy well, do he?"Yes, and the intent was to save money. Don't mythologize it. This ain't holy scripture. I'm sure D.C. Fontana would've loved to write the script in a way that included a visible ship if the money had been there. The producers of Star Trek wanted their show to look cool. Its visual spectacle, unmatched on television at the time, was one of its primary draws. But their ability to create impressive images was limited by their budget, so they had to parcel it out.
As far as the story goes, I think the new FX are perfectly consistent with the dialogue. In the early shots, while we can make out slightly more detail than in the original, it's still a tiny, blurry image on the viewscreen, consistent with Spock's lines about the sensors being unable to discern specifics. We didn't get anything close to a good look at it until the end when it came in close to attack the Enterprise. So I see no violation of "intent."
Frankly, @Christopher while I'm certain you're a perfectly nice guy in person, engaging with you online is rather like chasing Dino around the Flintstones' living room: always the same scenery in rapid succession and just as quickly tiresome. You nitpick things even when they are loaded with qualifiers, (e.g. LINK of a grand example), then you double-down when contradicted. You make semantic distinctions convenient to your position then balk when anyone else does anything remotely the same. Your arguments consistently imply knowledge and authority on virtually everything, even more so than people with actual practical experience with subjects that you have only Googled. Mea culpa and I are old companions, but your posting history suggests you've never met.
