I don’t see the conflict between the two scenes. Seeing the lightsaber makes Luke emotional. When he grabs the lightsaber, he throws it.
I don’t know what people expected, him to raise it in the air in that classic poster pose?
I’m going to be completely honest and say that was pretty close to my expectation.
But like I said, it’s Rian’s film, not mine. Don’t want to come off like I’m one of those “TLJ sucks!” trolls on the interwebs.
