Fan Casting Dull Surprise in Sort by Tropes

A vague, wispy look given by a character in response to something that, theoretically, should produce a more intense or specific expression of shock, horror, or revelation. Typically the situation gives the vibe that the actor or character should be surprised in some way, but their vacant gaze and lolling jaw is hardly what you'd call emotive. The trope is often used to describe the 'wide' range of emotions a given actor may use for a role, and one of the staples of lazy character design and artistry. Part of the "joke" is that the expression is extremely versatile, a standard movie poster look that never looks silly or awkward in a freeze frame, but often feels wrong in context.
