As the Resistance X wings are practically Ralph McQuarrie’s concept painting of them come to life, I have no issues with them.
The interior of the Starkiller did remind me of levels in the old Dark Forces/Jedi Outcast games. I half expected Kyle Katarn to show up.
Lest we forget, Vader himself has roots in old cliffhanger serial villains who are merely a guy in a scary mask disguising their voice.
I had never seen Skellig before or even heard of it before TFA. I imagine someone living in Norway gave the Hoth scenes in ESB a shrug? 😉
Not so subtle WWII imagery is nothing new in Star Wars either.
