Sonny Bunch’s review published on Letterboxd:
You know, I don't hate this exactly but I am kind of flummoxed by it. It's ... fine. McGregor and Robbie feel like they're in almost entirely different movies from everyone else? But the plot is totally paint by numbers, obscured by the overly complicated chronological nature of the plot. (It's like someone saw DEADPOOL and was like "ah, this is how you make an origin story feel fresh.")
You know when you are reading a Word document and you notice that the words are slightly larger or the font is just a hair off or there's a spacing issue that isn't present in the rest of the piece? And you realize, instantly, that it's been cut and pasted from a different word document (or website or whatever)? That's kind of what the fight scenes choreographed/shot by Chad Stahelski feel like: it's like someone cut and paste a different movie into this one every so often.
Honestly, I was just kind of bored by it for long stretches? Or, if not quite bored, certainly not engaged. It's not nearly as funny as it thinks it is and not nearly as edgy as the profusion of f-bombs would suggest. Eh.
