Lowbacca’s review published on Letterboxd:
Taika Waititi may not be the best Hitler, but he's certainly one of the best. And while part of it is that this isn't meant to be Hitler so much it's meant to be Jojo's perception of Hitler, Waititi still sells it. Just about the full cast really is quite impressive in this, with the possible exception of Rebel Wilson, which is less of a criticism of her performance and more that I don't think she's well-used in this. Somewhat similarly, I think Scarlett Johansson's good in this, and her character is good, but is a bit underdeveloped, particularly her relationship with Jojo.
When the movie is being funny, and it often is, it does a very good job of it. With Waititi, this isn't particularly surprising. Where the movie stumbles, though, is when it comes to some of the plot points, and a bit of a lack of subtlety. It could have been done a bit better with a little bit of expansion on some of the plot points, but the themes are still strong, even if the plot left me wanting a bit more detail.
Ultimately though.... I'm still amazed that this movie made it to theatre. With the concept of this movie being so Hitler-centric, this is the sort of thing that I didn't think a major studio would go for.
