I will say this up front: 'The Force Awakens' as a singular entity, is going to be a very well-made movie. The pacing, action, cinematography, acting, and CGI are all going to be absolutely amazing. But that is not everything that matters. There is one huge thing that matters more: Is the story really moving forward, or is it repeating everything from the original trilogy for no reason?
The main point of the original trilogy was the destruction of the Empire. The catharsis at the end of 'Return of the Jedi' hinges on the destruction of the Empire. The destruction of the Death Star and the death of the Emperor are obvious symbols of the destruction of the Empire. Why is this being retreaded in 'The Force Awakens'? You have to be dense to believe the First Order isn't merely a rebranded Empire. It is, and there's no two ways about it. It's derived from the same source, has the same motivations, operates the same way, and looks utterly identical. The only thing that's different is the name, which seems to be tricking everyone with nostalgia goggles, and this is a huge problem.
We already had two Death Stars in the original trilogy, and now there is a third one in the poster for 'The Force Awakens'. Why? Is Star Wars really supposed to be this repetitive? You guys aren't happy unless the good guys blow up a giant metal ball in every fucking movie?
In the new trailer, Han Solo says something about how the stories of the Jedi and the old war, or whatever, are "all true". This doesn't make any sense at all. For starters, the events in the original trilogy were not a secret. Secondly, the Jedi were already mythical and long-forgotten at the start of 'A New Hope'. The first 10 minutes of Alec Guinness's Obi-Wan Kenobi has him make a very clear point of this, as does the first meeting of Empirial officers when Tarkin refers to the Jedi as a "dead religion". This whole mythical element is the very thing that makes Luke such an interesting character, because he's going to represent the re-emergence of the Jedi. He's going to bring the Jedi out of mythical status, and make them real and remembered again. The title 'Return of the Jedi' means "re-emergence of the Jedi as a significant presence, by way of Luke." The title does not literally mean "A Jedi returns from having been absent", and it is proven very quickly due to the fact that Luke, as a Jedi, never left. He's a non-Jedi, and then he comes into the situation as a Jedi. So he himself is not a returning Jedi; he is the first new Jedi after a long absence of Jedi. He is the return of the Jedi. If the Jedi don't have a large presence in 'The Force Awakens', then the title 'Return of the Jedi' doesn't mean anything at all, and should be re-titled 'One New Jedi, Not that it Matters'.
Getting back to my first point, the death of the Emperor and the destruction of the Death Star are also symbolic of the destruction of the Sith. Sure, everyone keeps saying the Emperor and his exploits are not the only examples of Sith activity. Yes, I acknowledge that this is 100% correct; HOWEVER, within the context of the movies, the Emperor and his exploits represent the Sith's motivations and operations as a whole. The Emperor is represented as THE symbol of the Sith, and a strong point is made of destroying him so as to end the destruction caused by Sith in general. The death of the Emperor represents the end of the Sith. There is no need to keep exploring the minutiae of this within the movies - the minutiae is precisely what the Expanded Universe was invented for. Now, you might be saying "The Sith are not at all related to Kylo Ren", but you have to be incredibly dense to truly believe Kylo Ren isn't just a new type of Sith. He's evil, dresses in black robes, wields a red lightsaber, and has power within the Empire (which is simply rebranded as the First Order). Kylo Ren is a Sith, it doesn't matter if his organization has a new name. He represents all the exact same tropes as the Sith, point-by-point. So if Kylo Ren and his ideas are still being represented, then the catharsis at the end of 'Return of the Jedi' is rendered completely and utterly meaningless, because Luke, as a Jedi, didn't actually resolve anything.
'The Force Awakens' is retreading everything that was already done in the original trilogy, and thereby invalidating it. How does nobody else see this?
