Writer/Director Joss Whedon excels himself in this feature length version of his cult tv series Firefly. The writing is probably the best I have seen from Whedon. The characters are more developed than in the series whilst retaining the light, comedic feel that made the series so watchable. Some great action sequences that surpass Firefly what with Whedon having a bigger budget to play with. Ties up all the loose ends from the show nicely whilst also working as a stand alone film. Watching Serenity just confirms what a ridiculous shame it is that firefly was cancelled because if this was the way the series would have headed it would have been one of the all time greats.
