It's a very on-the-nose ending with overwritten, overlong dialogue explicitly communicating the film's themes. Alejandro also exposes Kate's breasts for no reason. The original script has a lot of brash, pointless nudity (there's another scene where the protagonist gets raped, entirely naked from the waist down before an officer comes to save her. That would later change to the more tasteful scene where Kate discovers that the man she's hooking up with is a hitman). The violence has no real emotional weight to it too.
In the final film, everything is much more subdued, dialogue is pared down significantly and the violence has meaning. Emily Blunt's passivity as a protagonist has greater weight to it too.
