Yeah I see your point. PT references have become more and more common after TFA. It might indeed be related to Dave Filloni getting more involved in LFL. It also can be related to the ST backlash and subsequent PT “aftermath” (re)appreciation (outside this site, I have noticed that most people actually like the PT and dislike the ST).
Bottom line is: PT references are actually a good counterbalance to pure OT continuity (and rehash in a way). It works fine. I’m less enthusiastic by new ideas that don’t really blend. On this particular show, I still can’t buy that Temuera is the same guy (physically and in term of personality) we discovered in TESB/ROTJ 😦
