Unsurprisingly, there’s a TVTropes for that:

> Admittedly, the reason for revealing only failed plans to the audience is obvious. There's no drama in something going wrong if no one knows what was supposed to happen. Conversely, where's the drama in seeing exactly what you were just told would happen? The only exception is when the plan is Crazy Enough to Work; when every bullet point could Go Horribly Wrong, then each success is a big, suspense-building deal. As a general rule of thumb, if things do go according to how the audience is told, you can expect that the characters are walking into a trap.
