I was actually thinking of Game of Thrones by the end of it, how they set up a cliffhanger and reason to come back with the way it ended. Which of course all started with Empire Strikes Back.
I can nitpick all of the Star Wars films (with love) for various reasons but the issue I and I think most people have with the new one is a more fundamental problem and that is that we were fed a recycled version (basically a remake) of a movie we'd already seen. No surprise I suppose given that it was JJ (MIssion impossible and Star Trek Into Darkness) Abrams doing it. I did not wait 30+ years from Return of the Jedi for the next chapter only to be fed a story I'd already seen but with various plot points jumbled around and passed off as new, as technically beautiful as this new film was. Empire was not the same story as New Hope, and neither was Return of the Jedi despite the otherwise common element of the second Death Star. They were all very different stories, as were the prequels, but united around certain age old themes. A Death Star is not a theme. It reminds me of the South Park episode where the military approaches Hollywood directors for ideas about how to defeat aliens and Michael Bay keeps saying "explosions" until the general dismisses him saying "Explosions aren't ideas, they're just special effects".
I enjoyed the prequels quite a bit and find this latest movie too small in scale and too derivative. At least with the prequels Lucas attempted to enlarge the story and show us a different point of view of the Star Wars galaxy. I didn't get that here, and that's particularly disappointing since I was really enjoying the movie due to the charisma of the new characters and the more original plot points right up until a certain planet appeared. At that moment I knew exactly what was going to happen from then on and the goodwill of the first half of the movie evaporated. I now understand why the prequels are so widely disliked. It's not because of Jar Jar, or midichlorians, or Hayden Christenssen. It's because they weren't exactly copies of the originals judging by the overdone praise many people are heaping on this recycled story as "fresh" and "original". They had better have something new up their sleeve for Episode VIII, because even the most awestruck fan of this story can only have it retold so many times before losing interest. And if their "original" idea is for Luke to say "I am your father" then I will laugh out loud in the theatre.
