i noticed so many references to the movies in this episode. the most apparent of there was when maul sensed a disturbance in the force right before sidious was coming in. reminded me of vader sensing obi wan on the death star
Also, when Savage was stabbed by Sidious, Maul immediately ran to his side and knelt besides his dying body, like Obi-Wan did when his own master was stabbed by Maul. I really liked how they drew parallels to Episodes 1 and 4. You can tell LucasFilm really put a lot of effort into this arc.
