The Empire Strikes Back
Yes, yes, he’s getting on a bit. But really, just watch as he lifts the X-Wing from the swamp. It’s a right old strain on him. All wheezing and miserable. And he’s supposed to be at the top of the tree Jedi-wise.
Also check out Yoda balancing on Luke’s feet. You don’t need Force powers to do that, just ask anyone unfortunate enough to have suffered through a performance of Cirque de Soleil. And when Luke gets distracted by his sinking X-Wing Yoda goes arse-over-tit. So he can lift an X-Wing off the ground with his mind but he can’t hover?
Judgment on The Force: Too inconsistent
A New Hope
The climax of the first (fourth) movie. All the other Rebel pilots have been twatted by the Empire and it’s all down to lady-boy Luke. So what happens, Obi-Wan starts twittering in his head so he disconnects the targeting computer and concentrates. Ka-blammo! He hits the mark so it’s straight off home for galactic tea and space cakes. But hang on. Didn’t Luke say in the pre-attack meeting that it couldn’t be that hard as he used to nail whomp rats on his t-16 back home and according to him, they’re not much bigger than two meters. So does that mean he could of done it without The Force? Certainly sounds like it.
