I'll repost my light spoiler review here as well
Somehow, with "Serenity," Whedon has managed to scotch tape and superglue "Star Wars" with "Dawn of the Dead." It sounds like a lazy pitch from a coked out studio whore, but that's essentially what the movie is. And that's as aptly as I can put it. With all the negatives and positives that entails. Meaning that if there were problems you had with "Star Wars" and if there were problems you had with "Dawn of the Dead." -- and trust me, there ARE problems in those movies--you're going to find them in this movie. I'm thinking you're just going to have too much fun in the meantime to really care. I mean, sit and think about it. The comic-book, cartoony action, leavened with depth, of "Dawn of the Dead," married to the serial, comic, high-action feel of "Star Wars" with maybe a pinch of "Star Trek" folded in, kneaded and baked til golden brown, and you've got "Serenity."
At times, the movie is too jokey for it's own good. Maybe Whedon's sitcom sensibilities, honed as a writer on "Roseanne," are getting too much play here. But when the lines and the performances he's coaxing out of his talent are as easy and effortless as they are in this film, it's easy to forgive. Especially since these comedic sidetracks aren't, for the most part, stopping to derail the tightly plotted narrative of this movie, and nor are they getting in the way of the tone, which glides easily from serious to snarky. There are certain instances where Whedon's direction stumbles, and poor Gina Torres (Zoe) near the beginning of the movie, has to spit out a line about as forced as Berry's in X-men, but aside from these 2 or 3 stumbles, the movie never breaks it's amiable, adventurous gait.
Being that the movie gets most everything right, it's easier to pinpoint the lumps in this finely woven tapestry than it is to categorize every winning moment that flashes by onscreen. There are some deaths in this movie that should have more weight than they do. There are some reactions to some pretty momentous events in this universe that lack the depth they seem to call for.
For instance, the break in characterization for Kaylee (Jewel Staite) during the climax of the movie. It'd be one thing if her ferocity felt natural, but she becomes, for a split second, the warrior goddess that Zoe is, but only for a quick one-liner sex joke. It's a good knee-jerk haha, yeah, but it feels cheap and unearned, even out of character for Kaylee (and yes, I know her official introduction to the Serenity was her getting nailed by the first mechanic) Following scenes play out as if this blip on her radar had never appeared. It's a little jarring and makes her character ring false for a bit. There are some emotional scenes that are cut short for the sake of a reactionary chortle, that probably need a little more space to breathe with, before we plunge back into the adventure. To use my Star Wars comparison earlier--at least there was some sad music and a second or two of reflection for Luke before he ran to a gun turret and started vaporizing bad guys, following the death of Ben Kenobi. There are not one, but TWO deaths in this movie, that Whedon's direction dictates are JUST as important to his characters as Ben's death was to Luke, but only a fraction of that gravity is attached. Hell, even the final frame of this flick is a punchline designed to subvert the weight the movie has actually earned at that point. Yes, I reflexively chuckled, but once the laugh left my throat, I wished the moment hadn't been spoiled as such.
Yes, these things make the movie feel a little more slight than it should, but this isn't really the fault of the actors, Especially Nathan Fillion, all assured calm and purpose, even while his character is enduring pure turmoil and confusion as Captain Mal Reynolds, Sean Maher, who practially jumps off the screen with intense focus as Simon Tam, Adam Baldwin, walking the fine line between cartoonish and colorful as Jayne, and Chiwetel Ejiofor as the icy-cold assassin The Operative. Ejiofor's calculating efficiency almost snakes this movie out from under Fillion and Baldwin in terms of sheer cool factor, but just barely loses out to Baldwin out-Perlmaning geek favorite Ron Perlman (who's Johner in Alien Resurrection is obviously a test run for Jayne) and Fillion's expansion on the Han Solo-like Reynolds.
The almost superhuman abilities of our heroes isn't a negative at all, and speaks to Whedon's ability to lull the audience into almost perfect suspension of disbelief. In fact, it's part of what makes this movie so fun.
That's not to say our heroes don't make it through this movie without a scratch, as a matter of fact Fillion spends about the last 20 minutes of the movie with a nasty looking bloody eyeball, earned during a particularly mean fistfight, and in the last 15 minutes, practically every member of the cast is shot, stabbed and bleeding all over the place. And yet they still get up, powered by sheer force of will, to save the day. It's that sort of superheroism that lends the movie much of it's well-earned charm.
The movie is likable. There's problems there, it's not a perfect flick, it teeters too far into the comedy realm for it's own good, some of the catching up to speed of newcomers is a little forced, and as such, necessitates Whedon introducing plot inconsistencies between series and film, and for old-timers, some of the characters might as well be cardboard standees for all they have to do--Morena Baccarin's oddly drab looking (and it's saying something to make THAT woman look drab) courtesan character Inara and Ron Glass' preacher character Shepherd Book are not much more than big flashing signs screaming "PLOT DEVICE AND NOTHING MORE." The effects work is pretty slipshod in more than a few places, but Whedon, with help from his effects and stunt teams, manages to nail the action more times than not, providing a fleet battle between giant space cruisers almost as deftly as Lucas pulled off the opening 10 minutes of "Revenge of the Sith" and learning where so many other directors, specifically Christopher Nolan, have tripped-up: The fights really ARE better if you just pull back the camera a little. Summer Glau, who turns in a solid performance as psychic (and borderline psychotic) River Tam, whips ass in this film like a hopped up Buffy Summers times 2. I have a hard time believing either Sophie Okonedo or Charlize Theron will be able to impress as much in "Aeon Flux' later this year.
But it all comes back to this. The different flavors of fun provided by both the space opera of "Star Wars" and the zombie horror of "Dawn of the Dead" actually DO taste pretty decent together. I'm not saying this movie is as good as either of it's primary stylistic forebears. Not at all. But a decent percentage of the fun to be had in both movies is also present here. Joss Whedon's directorial debut is an assured one, and even with the drama-shorting ending of this film, he successfully left me wanting to see more of this universe in a darkened theater.
