From what I remember, it's all one long (I don't think it was entirely continuous) camera shot full of character introductions, so that makes sense.
"someone on another board was saying that they would probably wait for the DVD sales figures to decide wether to invest in sequel/s."
To my knowledge, the TV DVDs have sold well (200,000+ units). I can't imagine that the theatrical version won't do well either.
Some reviews at www.browncoats.com
'm not going to say it's the best science fiction movie, ever.
Oh, wait. Yes I am." - Orson Scott Card
5/5 "The first masterpiece of 2005" - Stefan Halley Hero Realm
A+ "Can proudly be placed alongside “The Empire Strikes Back” and “Blade Runner” as one of the best science-fiction movies of modern cinema." - Edward Havens FilmJerk.com
"Scene for scene, 'Serenity' is more engaging and certainly better written and acted than any of Mr. Lucas's recent screen entertainments." - Manohla Dargis New York Times
4/4 "'Serenity' earns director Whedon spot on sci-fi's Mount Rushmore" - Peter Hartlaub San Francisco Chronicle
A- "It's equal parts deadly action, deadpan comedy and knotty mystery." - E! Online
4.5/5 "The film is teeming with an overwhelming amount of integrity, heart, soul, and some of the best written characters to invade genre fiction in quite some time." - Spence D. IGN FilmForce
3.5/4 "[Joss Whedon] makes the smart choice to create drama through character development rather than action." - Lawrence Toppman Charlotte Observer
3/4 "Serenity is made of dubious but energetic special effects, breathless velocity, much imagination, some sly verbal wit and a little political satire." - Roger Ebert Chicago Sun-Times
"Serenity" flies with sass and spirit, qualities that have been in palpably short supply in that "Star Wars" series since, well, "Star Wars." - Jan Stuart Newsday.com
I love that last one.
