Luke throwing lightsaber over shoulder was...

Made one of the most poetic and powerful scenes in movie history a complete joke.

I liked it enough. However, it was a little rude, and a weird way to break the mood.

An amazing cliff hanger turned into a throw away joke.... pis poor writing IMO. If I were Kennedy I would have fired Rian the moment I read that line on the script.

It's like a quick cheap laugh followed by a puzzling angry emotion of... really did I just see that in a non parody star wars film.

I hated it. It showed disrespect to Rey. Someone hands you an object that you recognise but haven’t seen for many years and probably thought was lost, and you don’t ask who the person is, how they came by it, or what they want? If you’re a rude asshole maybe. Luke might be a lot of things, but he wouldn’t just dismiss someone out of hand like that.

It made sense for where he was emotionally and spiritually. Going by his expression at the end of TFA and the fact that he has been in exile, I think it's obvious he wasn't going to want to train Rey at first. I expected him walk away or something. This was unexpected but I didn't mind too much.

Luke throwing lightsaber over shoulder was.... Disney's declaration of intent on how they are handling these films moving forward. They just wanted the brand name. Not the story.

I was fine with it. I thought it conveyed exactly how Luke felt about the whole affair.

It's more involved than being a joke, which is quite interesting. After Rey presents Luke with his lightsaber and steps back to wait on his response, Luke spends a good ten seconds looking at it and then her, and only then does he nonchalantly throw it over his shoulder and walk away to his hut leaving Rey in awkward silence. It reflects his distain for the Jedi and probably for her at that moment. The move was unexpected and seemingly satirical when we were expecting a kind of serious emotional scene.
