Well, the serials that George was evoking followed one central set of characters through the series. They didn't do half a dozen about Flash Gordon and then have one about the guy piloting the next ship over. So in that respect, they're sort of straitjacketed by that original core premise. Some definitely see that as too restrictive. I'm one of those writers who likes the challenge of seeing what I can do inside of a scaffold like that.
As for the repeating elements, that's also George's vision they're following. "It's like a poem -- it rhymes". I don't mind George as idea guy, so long as others are doing the actual writing and directing.
For me, it comes down to that there will be people who applaud the current creative people for following George's original guidelines, and there will be people who want all Lucasian influence jettisoned. No, I don't think they've nailed it. Yes, I have issues with some of their creative choices (Rogue One should be a numbered episode, with some effort to better tie it to the throughline, they dropped the ball in covering what happened between ROTJ and TFA, plus many George-related rants), but overall I enjoy the basics of the stories we've been given, and have since I was two years old. *shrug*
