I suspect the hardcore Whedon fans will love this, but others will be left cold. CHUD.com had an early review of a test screening, hardcore Whedon fans loved it, those who didn't know him from Adam (most of the universe) thought the movie was "Star Trek Motion Picture Bad."
Actually you're distorting the facts. The article in question at CHUD wasn't a review at all, just an article commenting on the test screening reviews showing up at Ain't It Cool News (FYI: all positive). It was never referred to as "Star Trek Motion Picture Bad". The author of the article, Devin Faraci, commented that he heard from a couple of people he knew in the industry that thought "it was more Star Trek: The Motion Picture than Wrath Of Khan". Prior to that he had been down on Serenity box office chances and conveniently, he never backed up those statements any further, even when pressed for more details on Chud's message boards. Bottom line is, Serenity has been getting killer reviews, yes, from fans but also quite a few people who are unfamiliar with Firefly. Hell, reportedly, even Kevin Smith attended one of the screenings and was impressed.
