Aidan Fealy’s review published on Letterboxd:
'Serenity' is a refreshingly distinct contribution to a saturated and, at times, rather tired action/sci-fi genre. I'm impressed with the world-building that Whedon accomplishes here, especially insofar as it's related to the series it was born of. To make any movie with ties to a beloved (and limited) series is risky business, and the team that made 'Serenity' did it with integrity, commitment, and a dreamer's temperament. Good one 'em!
