To be fair I can see where elements from the original trilogy were picked up just from this comment alone from at least the first two films, though I think there's enough differences between them to make them distinct from one another.
- Yes, Jakku is a desert planet, thing is you don't really see C3PO or R2D2 going up to some robot ranch to find Luke Skywalker, instead you have a Finn betraying the Storm-troopers since he probably hasn't seen much military action and saving Poe and his droid BB-8 crash landing there to find some shit hole poverty stricken area to ding Rey who happens to be searching for parts on a destroyed Imperial Empire ship. And Rey doesn't exactly have any family she's living with she's just stranded out in the middle of nowhere.
- To be fair, I can't really say that Han is much of a mentor figure in the same sense that Obi-Wan Kenobi is to both the Skywalkers or Qui-Gon Jinn is to Obi-Wan. If anything he's just getting dragged along into another mess and helping out Finn and Rey as much as he can and confirming the fact that Luke is still alive. Sure, you could argue that he has gained some knowledge of the force but bear in mind he probably knows it just from sticking around Leia and Luke some time during Kylo's training with Luke, doesn't mean he really teaches anyone how to use it. You could also make the argument that he gets killed by Kylo-Ren like Obi-wan died to Vader/Annakin and how Qui-Gon died to Darth Maul. But what sticks out about Han's death is that he's getting killed by his own son instead of someone who is related to him.
- On another subject about the mentors though, the one where Rey is trying to find Luke is being drawn as a similarity to Luke finding Yoda, that is true. Consider that Rey never really had a proper mentor for one. Most of the time she pulled the force out of her ass and went through trial and error in order to get by in the starkiller base and being able to pull off a jedi mind trick in three tries. I'm assuming she picked some of this up in the force vision she had from holding Luke's old lightsaber that somehow came into the hands of an alien some time after the end of the Empire Strikes Back where it fell millions of feet in the sky. This is one massive difference between her and Luke that I don't think many people realize.
-The Battle on the Starkiller base is pretty much a frozen waste-land battle that is actually, a hybrid between the Death Star Battles and the Battle on Hoth. But there's no AT-AT walkers so that's a big enough difference for me. Also Finn and Rey fought Kylo Ren here before the base blew up.
-Did I mention that the Starkiller base destroyed a whole system that was witnessed by everyone compared to one planet being blown up and then just one jedi saying "I feel a disturbance in the force"?
-Also the only difference I can see in the fight on that took place on Takadana and Endor is that instead of Ewoks, you get TR-8R, this badass over here:
One could make the argument that this fight between him and Finn is the only political reference in this movie but that's another story. The real point is that you have a fucking stormtrooper fighting someone using a light saber and not a typical jedi fight.
So we all good covering some of the differences here? good.
