The movie is good. People are exaggerating over the fact that "they could have done a better job". I don't understand why they can't just sit back, relax, and enjoy a good movie.
We finally get some answers from previous episodes and can understand the purpose of several characters throughout the saga.
My recommendation is to go with an open mind, and a happy mind, stop being so negative and always pointing out the bad; It's kinda interesting to see so many people becoming top cinema critics once a new movie comes out.
