I didn't particularly like the film overall (liked it better on my second viewing today though), but don't loathe it because I think there were good things about it also. I geninely liked Luke's character in it, so I'm getting Luke. I mean, it's Luke.
Liked Rey as well, so I'm getting her Jedi (not training) outfit, and that's all I'll get from her being I already have TFA RO Rey. I liked Kylo also for the most part, but already have TFA Kylo and like that look better, so I'll pass on TLJ Kylo. Most I'd do is just get a TLJ sculpt for my TFA figure, even if the scar is inaccurate. The scar I think gives him more character and depth.
Unless the Leia sculpt is improved, that's a pass as well.
Any other character is an easy pass for me as I had no interest in them in this film.
So likely just Luke and Jedi Rey for me.
