In defense of the new Star Wars, there are 2 reasons why the basic plot is so similar to A New Hope. The first is obvious, it's the first time they've made a Star Wars movie in around a decade and with all the negative feelings from the prequels they had to show the audience that they can do something that feels like Star Wars, and mimicking the original is as good a way to do that as any. The second is actually to show the cycle of history (to paraphrase an anime, "history is like an endless waltz, the 3 beats of war, peace, and revolution repeat themselves throughout the generations.") Star Wars is also in that waltz, episode 1 started with the revolution from the separatists, the clone wars was the war, and revenge of the sith was peace (with the empire in control.) A New Hope was the next revolution when the rebellion fought back against the empire, followed by the war of the Empire Strikes Back, and peace in Return of the Jedi. The Force Awakens is the next revolution phase as the First Order tries to re-establish the empire, the theme of the cycle of history is preserved.
That said, the next movie shouldn't be a re-tread of Empire Strikes Back, that would be just plain stupid given the situation the characters are facing now.
