Dov Doviak’s review published on Letterboxd:
Overall, Megan Leavey is a thoroughly average, by the book feel good biopic, and while there's nothing inherently wrong with that, I rarely find myself enjoying this particular genre. That being said, I definitely dropped tear watching this... Looking back, I'm not quite sure why, (especially since I thought the majority of themes were explored in largely unsatisfying ways) but it definitely happened, and deserves a star bump because of it. One thing worth mentioning is that the dog(s) acted circles around Kate Mara, which isn't a dig at the lesser Mara (though that was), the dog performance was just that incredible.
