The ending was a mistake (spoilers)
Firstly, it’s weirdly ambiguous as to whether Wick is dead. He tells Winston to ‘take me home’ - does he mean literally, or carry his dead body, or be with him as he dies? If the latter two, where did Winston disappear to?
Nevertheless, it looks like the filmmakers killed John Wick. If so, they should have devoted more of the ridiculously long runtime to his death and its wider significance. It felt rushed and messy.
But I think killing off Wick was a mistake. Why would this relentless and invulnerable man decide to keel over moments after finally winning his freedom? Plus, his wounds were not fatal (in this movie universe anyway). If you’re going to kill him, make it concrete that he’s dead.
Finally, we don’t need any more straight white male heroes killed off to make way for ludicrous female action heroes like this ‘Ballerina’ we’re hearing about. If Keanu’s finally hanging up the bullet proof suit then at least leave the character alive in the popular imagination.
