I’ve said it a million times but finding Luke IS the conclusion to the story.

Actually, TFA stands pretty well on its own without the others (lot of new fans have seen TFA first). There are a few more loose ends at the end than say ANH (Kylo, Snoke, Hux, Finn vs. Vader) but finding Luke is not one (insane to me that people think removing meeting Luke is somehow getting rid of a cliffhanger when it’s actually making one where there wasn’t one before).

If someone wanted to make the film more standalone, it’d be pretty simple. Change the crawl, trim the Han stuff, do something different with the Force vision, and remove Snoke telling Hux to get Ren (and therefor imply his death and the possible destruction of the First Order). Might be an interesting little edit.
