You'd think celebrities would be able to dust off bad reviews like they were ain't no thang -- but not Ben Affleck.

During a press event for his widely panned film Batman v. Superman: The Dawn of Justice, both Affleck and Henry Cavill were asked about the film's mixed reviews.

In the hilarious video, Cavill keeps chatting while the camera focuses on a forlorn Affleck now called "Sad Affleck" as he looks to the ground.

Seriously -- it's cringe-worthy heart breaking stuff!
