I’m not sure what you’re referring to when you say TFA reuses dialogue from the OT.
referring to the millennium Falcon as ‘‘that hunk of junk’’ for exempel.
Isn’t that called a running joke?
What I think people seem to have trouble getting their head around is that TFA and R1 are largely getting the Star Wars ball rolling again. After the bad taste of the prequels, Lucasfim figured that people needed to be reminded of what made Star Wars great. New stories with interesting characters we actually give a stuff about, and give a stuff about each other. It also needs to walk that fine line between making it feel like a Star Wars movie used to feel and blatant fan service. Sometimes they got it right sometimes they got it wrong. The largely positive reaction to the films however, suggests that it was more the former than the latter. Critics will still use this as ammunition and cite any reference to the OT as fan service. But I contend if it were all about fan service there are a lot of things Lucasfilm could have included to get the fans drooling in their seats.
I really think that people are going over the top with this Disney = corporation = bad bs. Yes they are about making money but to do that they have to make entertaining movies. Kathleen Kennedy has a massive say in how these movies are put together. You know, the producer of such poorly received movies as Raiders of the Lost Ark, ET, Schindler’s List, Jurassic Park… She is helming Lucasfilm and is a highly respected filmmaker in her own right. While she ultimately answers to the Disney executive, her thoughts, opinions, and recommendations are highly regarded. There’s no way someone like Kennedy would still be there if they weren’t.
