If it is indeed a rant then it's one that's completely justified, imo. The real issue was that during the movie's initial release criticisms were typically hand waved away with that whole "you don't like a female lead in your nerd movies!" thing. That may have been true for, like, five percent of the group of critics, but that still leaves ninety five percent who were a mix of people that were displeased because they felt that the movie was a ham fisted attempt to rake in money from nostalgics, people who felt that they threw away well established and, frankly, more well rounded and likable characters for the shiny new kids, and people that were simply really, [i]really[/i] pissed about Han. 

I'm truly worried that they might get into the habit of crying wolf while they decide to pump out a bunch of cash grabs by introducing new characters to make later origin movies for rather than expanding on pre-established characters, and that the series will suffer for it. I want my Han and Chewy movie damn it! Hell, i'd be absolutely over the moon if they did anything Grievous related that didn't butcher him to hell and back like last time.
