Bad guys and good guys constantly come up with plans to achieve their goals, especially in action movies and heist movies. But often if you think about the plan a little, you realize they're often terrible plans that made little sense. The writers want you to think these plans are brilliant, but they only worked out because the plot says so.
They all too often rely too much on luck, things going exactly as planned, enemies acting exactly like they need to, and predicting things they couldn't have possibly been able to predict. It's especially bad when the plan relies on getting captured by the enemy.
What are some notable examples of terrible movie plans?
Using dangerous animals as military weapons, most painfully stupid in the Jurassic world movies, but also kind of in the alien movies.
In Jurassic World they say they can let the dinosaurs loose in the kind of cave systems Al queda hid in. Thats pretty stupid already. You’ve identified the exact connected cave system your target is in and your idea is to put animals in it? Ok. It’s taken to its absolute idiotic extreme in the JW sequels wherein they need to hit the target with a laser pointer from a thing that looks exactly like a gun, and that will make the dinosaur chase the target. If you had just pointed an actual gun at the target instead of the laser tag gun, the target would have already been shot by a gun.
