To find the best thrillers online, you can't be limited to a single streaming service. Otherwise, you run the risk of missing out on the films that didn't get the attention they deserved when they were first released. The Watch With Us team has chosen the three underrated thrillers that you should watch in August, and it's a really good batch of films this month. Our first selection flew under the radar earlier this year, while our second pick is a Netflix original that's skipping theaters. The final selection for the month is a largely forgotten film with one of Hollywood's greatest actors.
