It stands out as a film that's sparked a buzz in both critic and viewer circles. Metacritic's aggregate score reflects a generally favorable reception, with a Metascore of 86 based on 57 critic reviews and a user score of 7.0/10, indicating a positive audience response.

Critics praise the film for its unique perpetrator's perspective on violence, professionalism and a profound exploration of the assassin's psyche, which is both chilling and humanizing.

David Fincher's direction is lauded for its methodical control, contrasting with the protagonist’s flawed logic and self-knowledge. However, some note that the film's pacing, balancing tedium with tension, may not appeal to all audiences.

Critics from Rotten Tomatoes echo similar sentiments, underscoring Fincher's stylish direction and Fassbender's compelling lead performance.

The film is described as a perfect match for Fincher's directorial style and Fassbender's acting prowess, providing a stylish and engaging thriller experience. However, audience opinions vary, with some finding the film a bit dull or pretentious, despite its appeal to Fincher's fans.

Other reviews highlight it as a production that works both on big and small screens, engaging viewers with its plot development and Fassbender's magnetic presence.

Despite the inherent familiarity of the hit-man genre, Fincher and screenwriter Andrew Kevin Walker have crafted an absorbing tale with a focus on the finer details rather than just action-packed sequences.

However, some critics feel that Fincher's obsession with filmmaking technique might overshadow deeper thematic exploration, and one critic even describes the film as a "sleek, tight, fastidiously executed nothing".

In sum, The Killer emerges as a film that's not just another addition to the hit-man genre, but a cinematic piece that delves deep into the psyche of its protagonist, backed by Fincher's distinctive directorial style and Fassbender's strong performance.

While it might not resonate with all viewers, especially those seeking non-stop action or conventional storytelling, it offers a nuanced, stylistic, and thought-provoking experience for those appreciative of its unique approach.

The film, with its blend of style and substance, is indeed worth watching for those intrigued by a deeper, more cerebral take on the thriller genre.

What happens at the end of The Killer?

The climax involves the Killer sparing Claybourne, the client who ordered the hit against him. This action suggests a potential shift in his character, hinting at a desire for a more normal life with Magdala (his girlfriend).

The ending is ambiguous. It's unclear whether this decision is a step towards retirement and a normal life or a strategic move to maintain his career prospects as a hitman.

The film ends with the Killer contemplating his future, indicating a significant evolution in his mindset and priorities.
