I don't have a problem with references of the 90s anime when they are an enhanced version of the original. Crystal season 3 copied the inner senshi attacks and the outer senshi transformation, but couldn't even meet with the quality of the original. Of course we've only seen a low quality glimpse of the "new" attacks. They look more fluid then season 3 and 90s attacks, but the faces, bodies, lights and shadows are way superior in the 90s anime.
