This is the kind of reductionist shit that so many of us are sick of. You point to the obvious callbacks and homages, and ignore the context around them. "Look, this thing is like other thing. I recognize thing. I did it." TFA is only a copy of ANH if you point to the obvious surface level stuff. But if you actually point to what the movie is about, how it is about it, like, the actual story the movie tells, the journey the characters go on, it's completely new.
There's way too many "homages" if you think they didn't use ANH for the overall plot structure.
1. Main character living on a desert planet unaware of their past or that they are force sensitive.
2. Droid with a super secret message hiding within it.
3. Droid finds main character and starts them on a journey.
4. Hero tortured to find out information (Poe/Leia)
5. Secretive villain who's over the villain of movie (IE Snoke/Kylo vs the Emperor/Vader)
6. Main villain wears a mask
7. Older figure who main character looks up to to find answers and learn from (Han in this, Obi wan in ANH)
8. Villain of the movie cuts them down while the main character looks on and can't save them.
9. Giant round weapon meant to wipe out planets, but with a fatal flaw to its design.
10. It's weakness is beat by an X-wing firing into this weak point.
There's plenty of good movies that pay homage to ones before them but are still their own movies when it comes to the basic plot structure and overall story.
TFA was played safe in this aspect.
Rogue One on the other hand was not and it was the better for it, imo. I hope that Ep 8/9 aren't afraid to be more of their own movies in this regard, it's ok to have a homage here and there but they need to have their own story.
