Star Wars Episode 6: Return of the Jedi - He's Faking It...
At the very end (nearly) when Luke and Vader are fighting, it's all pretty well choreographed. Then it falls apart. Vader DOESN'T get defeated, he just backs up and sits down, ready for Luke to cut his hand off. Don't believe me? Think I'm nitpicking? Watch it for yourself. You will cringe.
This is not a slipup. You see, Jedi have special training to predict things before they actually happen--a good ability to have when fighting. This way they can estimate when someone is going to take a swing, etc. So you are wrong, my friend.
