Speaking for myself, I'm not concerned with Luke being portrayed as weak nor do I expect the new films to resonate with me the way that the OT did. My reason for hating The Last Jedi is that it was simply not a very good movie. I realize that Game of Thrones is popular, but having several scattershot subplots interwoven throughout a 2.5 hour long movie doesn't make for compelling fiction, even when riding the coat tails of a popular intellectual property. The dialogue was horrendous, and filled with exposition. The plot was unimaginative and anti-climactic. The character design and CGI was underwhelming; Yoda actually looked like a deflated chew toy. The movie was boring, and it failed to achieve pathos.
Worst of all, many of the ideas driving the plot were, frankly, dumb. The worst example: At the end of the movie, why would Luke refrain from telling the rebels to run for their lives, while his Force Ghost PRETENDED to fight against Kylo Ren and the First Order? Luke assumed they'd figure it out for themselves? Seems irrational. You'd think giving them a head start would be constructive.
Edit: I changed my mind. The worst idea was having Yoda's Force Ghost capable of affecting the tangible world. This undermines the logic of the ENTIRE Star Wars franchise.
