There used to be fans who argued and fought over the size of the unfinished second Death Star as compared to the first one. Also, the actual size of Vader's Executor Super Star Destroyer. But compared to most of the nuEnterprise stuff we've been reading?

Hrm. Of course. It's not the same thing at all. Star Wars is science-fantasy. It has as much scientific credibility as the Muppet Show. Star Trek, on the other hand, is pure, unfiltered, cerebral science-fiction, a perfect extrapolation of the future of mankind, and every single detail is crucially important.
