WOW! How I wish I had caught this at the cinema. This is the movie that followed on from the popular (But cancelled...) Joss Whedon TV series Firefly... And it is so well done. Whedon has done the near-impossible in managing to bring newcomers into the film with a short intro that gives them everything they need to know, while also giving fans of the series all of the elements that they love, no contradictions to what they know, and not boring them with stuff that they knew by heart. Brilliant!
According to the docos that accompany the DVD, the film was made on a (Hollywood) shoestring budget. (Hollywood shoestring is different to any ordinary shoestring in being so very much larger!) Despite this, the special effects are totally convincing (as they were with the series, but as some lower budget movies fail badly in this, it is interesting to note.), and the sets are almost identical to those from the series, even though these were trashed after Firefly's cancellation.
It is a testament to the love that the actors have for this show, and this universe, that the entire series cast was able to re-assemble for the movie. Their performances are so true to the original series that it is hard to believe it has been three years since they were last together.
If you are already a fan of Firefly, this movie will leave you wanting more. If you have never heard of Firefly, but like Joss Whedon's other work (Buffy & Angel), buy the DVD, watch it, and then you'll be buying the Firefly box set. If, on the other hand, you have no idea about Firefly or you are asking "Who is this Joss Whedon character, anyway?", then rent Serenity. You may just be about to go into a major DVD buying spree... or you may hate it. But if you don't try it, you will never know!
