There aren't many days left in September, but there's still enough time to catch a handful of thrillers before the end of the month. The Watch With Us team has chosen a trio of underrated thrillers on Netflix, HBO Max and Prime Video that should close out your movie nights for the month. Two of our picks are celebrating their 30th anniversary in 2025, and they couldn't be more different from each other. Our final pick is a film that really should have done better in theaters. But now it can find the audience it deserves.
