The Main Problems with "THE LAST JEDI" can actually be Fixed Very Easily

Honestly, most of what you mentioned are not the main problems of The Last Jedi. Maybe they are for those Star Wars nerds who spent so much time speculating and theorizing about things from TFA, but not for those outside the hardcore fan base. The film's main problems are it's terrible central plot, non-existent character development outside of Luke and Kylo, and it's boring, pointless side plots. Those things are not easily fixed. The next movie may turn out great but it won't turn TLJ into a good movie.
