Why couldn’t Vader have caught Luke in his fall?
Why couldn’t the Emperor have floated back up to the platform?
Why couldn’t Luke have thrown the Rancor across the dungeon?
Why couldn’t Luke have bent the bars to let himself out of the Rancor’s dungeon?
Why couldn’t Luke levitate Lando out of the Sarlaac pit?
Why couldn’t Luke push all of Jabba’s bad guys into the Sarlaac pit?
