Matthias Bergleiter’s review published on Letterboxd:
What a fucking ugly movie. Not necessarily in its aesthetics, but JFC this is bleak. Ayer does not seem to have an ounce of humour in his body. Well, we knew that from when he tried, of course, but it is still baffling.
But on the other hand, it's testosterone drenched disgustingness (a word?) is kind of enjoyable. Sabotage does not pull its punches when showing its protagonists as fairly despiccable human beings, while telling a story about the probably ultra rare moments in their lives when they are still slightly relatable. It's far from great, but it just works.
And then there is Joe Manganiello. I have no clue why he does not have a career similar to that of Jason Statham yet. He's made for this.
