Ask ten people why they didn’t like TFA and you will get ten contradictory answers.
Well, they are ten different people; they’re bound to have their own differing tastes and biases …
Yeah, but if there really was a big underlying problem in the movie, these complaints wouldn’t contradict each other so much. Among the people who don’t like the PT, there is at least a general consensus about what exactly is bad, not someone saying “Jar-Jar was stupid and unnecessary!!!” and the next one saying “Not enough Jar-Jar scenes!!!”.
In the case of TFA, it’s all about personal preferences and interpretations, not about things that are truly objectively bad. Notice that I didn’t say “what they don’t like about TFA”, sure you may not like villains to have a personality apart from being evil, but this doesn’t mean every movie that has such a villain is bad.
