Tim Brayton’s review published on Letterboxd:
I'm sure I did it no favors by watching it directly after finally catching up with Waititi's Boy, a movie that does many of the same things and does all of them better. It's especially galling to compare the two films' control of tone: Jojo has a huge problem with this, never quite finding a reliable approach to mixing broad slapstick, dark comedy, anachronisms, sentimentality, and horror at the real history underpinning all of the above. This is more of an annoyance than a huge problem for most of the running time, but the film goes all the way off the rails in the last act (you can pinpoint the exact shot where this happens), failing miserably to adjust to the bleak new tone of the darkening material when its heart is clearly still in goofy jokes and light childhood adventure. Thomasin McKenzie is great and Waititi-the-actor has the benefit of knowing exactly what his director wanted, but I'm not as impressed with the acting as I've heard I was going to be; the film's accents, in particular, are going absolutely every which way, and it gets in the way of some of the line deliveries.
