Serenity was a great movie! I'd only seen a few episodes of Firely, so I only knew a little bit about the characters, but the movie does a great job at showing you who they are. Even if you don't know what they're like it shows their personalities so clearly (yet without overdoing it), that you can still get all the jokes and moods of everybody. Also the story was welldone too, so even if you never saw the series, you can still pick up on what the movie is about and such. The cinematogrophy was great as well. There were many interesting camera angles and special effects that didn't hinder but rather helped the scenes. Also throughout the movie there were many unexpected and unpredictable things that happened (including lots of jump scenes, so beware). The dialogue was very well written and thought up (as if they'd actually put time into, unlike another space movie we've seen *coughstarwarscough*) and the characters all had personalities (unlike another space movie we've seen *coughstarwarscough*) and although the visuals were great, they actually spent time on the story rather than making it an eye-candy CG movie (unlike another space movie we've seen *coughstarwarscough*). ..oh yeah, and also the acting was very good too (unlike another...yeah you know) So basically this movie owned and I recommend it to anybody who enjoys a lot of comedy, action, violence, and jumpscenes. ...and sci-fi. (oh and there wasn't any nudity, and the sex-jokes were extremely scarce so that automatically gives this movie a lot of happy plus signs. There was one scene where they were kissing and stuff was implied but ummm...nothing more than that)
