I think AngryJoe and many other YouTubers point out how awful it was for Luke to toss that lightsaber like that, but their reasons for not liking it actually work in favor of Luke discarding that saber. They say things like, “THIS LIGHTSABER HAS BEEN PAST DOWN MANY GENERATIONS, IT WAS THE ONE HE USED AGAINST VADER AND WHERE HE LOST HIS HAND!!!”

Whenever that’s mentioned, it’s comical to me to think that’s their reason why it shouldn’t had been tossed by Luke. To Luke, it’s a weapon that is tied greatly to bad memories, so of course he wouldn’t praise it like the Holy Grail as fans do.

However, I do think it’s very odd to have that scene done in that manner. It literally feels like a gag lifted from a YouTube parody video similar to this: https://www.youtube.com/watch?v=dXlao2KNYjQ

So I’m totally on-board of why TLJ’s Luke doesn’t respect the saber, but surely there could had been a less comedic way of doing so?
