5 second plot: Wade Wilson is an ex-special forces soldier who transforms into an unkillable, but very likable mercenary with a big mouth after they experiment on him to cure him from cancer. He helps the innocent (but also sometimes probably accidentally kills one) and punishes (let's say: kills) bad guys.
5 second review: I laughed my ass off. The entire theater laughed his or her ass off. The crowd simply went wild. That doesn't happen very often. It's brilliantly funny.
