Most critics respond positively to Swan Song, with praise centred on Mahershala Ali’s restrained dual performance and the believable near-future setting. Even several detractors find emotional credibility in his portrayal of two versions of one man. The warmer reviews describe a thoughtful, moving drama about mortality, family and selfhood, with science fiction kept close to ordinary human concerns. Variety also praises the chemistry between Ali and Naomie Harris.
The spread is wide, however, and the main disagreement concerns how fully the film develops its premise. Admirers value its restraint; less persuaded critics find the relationships thin and the emotional payoff insufficient. IndieWire finds the film moving but regards Poppy as underwritten, a reservation echoed elsewhere in concerns about Harris’s limited role. The AV Club is more firmly dissatisfied, arguing that the ethical dilemma remains underexplored and that Ali’s performance cannot compensate for inert drama and overly explicit storytelling.
