Questions and Answers and Storytelling

You know, for me at least it really doesn't bother me when trilogy movies leave you with some questions as you can expect most of those to be answered in the following movies. In all fairness and defence of TFA, I really have no idea why fans act this way. True that the movie has lots of things we would like to know but wasn't it the same with the other movies? Just using the OT as reference, when we see the ending of ANH, our heroes are in Yavin 4 celebrating their victory. Suddenly when we see TESB, Yavin 4 is nowhere to be seen or even mentioned and our heros are in a frozen planet. The bad guys seem to be back and as powerful as ever and Luke even knows telekinesis when that was something he had never seen Ben do and I always asked myself how could he do that. The good guys also seemed to have lost all the ships that they used in ANH and were now flying these cool little two man fighter ships. Same thing happened when ROTJ came along. At the ending of TESB we see Chewie leave with Lando to rescue Han and Luke has lost his lightsaber. When Jedi starts we see Lando inside Jabba's court as a spy and Chewie turns up later with Leia. We are surprised to see a new almost completed Death Star and once more we are baffled with Luke as he now had an awesome new green lightsaber which led fans to so many questions. How did he get it? Did he build it? How did he know how to build it in the first place? And so on so on.
