The whole premise of humans being the strong ones in the force is laughable in these films anyway, in that way the prequels made more sense with so many of the Jedi Council being non human as lots of them lived longer. Anyway took my son to see it today he loved it, I didn't but the failings are nothing to do with the makers as such and more me never being able to let go of what I thought should happen. The EU story for Luke just makes more sense but has become impossible with how late they left it so I can see totally why they have gone this route.
The EU also ran into the problem of you have X as a powerful Jedi that every story was just waiting for X to swoop in and save the day. Which for me is why they would have been better off at this point having a Jedi council and academy that Luke trained and then kill him off. Leaving more than one girl to take the story forwards, they also have to conjure up another ridiculous quick jedi when she doesn't want to do another film. I just don't feel what they have done is as strong as the backbone of the EU.
My son loved it and that's all that matters, but I'm checking out of anything going forwards now. It's just not for me. I think what will shine for me is every thing they can make pre-sidous, kind of old republic stuff Jedi vs Sith as it will be new ground and none of the characters I have become attached too. I just don't care about these characters. I thought it was much better than TFA, but if I never see it again I won't care.
