You know, I get that you build this movie up for a large part of your life and imagined all these things that sound cool to you, but did you honestly expect the actual creators of a new movie to follow your very specific ideas? I honestly don't think that's a healthy attitude to these things - and the chances of George Lucas specifically following your ideas if he made the movie would also be very small. (and, again, for the record, George Lucas wasn't cheated out of Star Wars - he willingly sold the franchise for 4 billion(!), and a lot of the original creators of the movie still worked on this one. Just not George).
Instead, it would probably help your own enjoyment of the upcoming movies if you just try to remain open to what the new writers/directors have to say. Honestly, they're not secretly out to destroy Star Wars. And the fact that TFA was so reminiscent of ANH (which, I agree, went too far in places) wasn't something they did by mistake or something they thought they could get away with, but a very deliberate choice. It may be a good or a bad choice (I think it's somewhere inbetween, nudging towards good), but it wasn't done out of laziness or hate towards the franchise.
And, like others have said, during the OT almost nothing about how the universe worked was explained. That was part of the appeal. The PT (and EU) tried to fill in a lot of those gaps, and I think they went too far with that because by explaining it so much it just makes the universe feel smaller. Something I think Kasdan also commented on at a time.
