its going onto hbo max iirc
and I really hope season 15-18 get full volumes cause I guarantee that I would like 15 and 17 more if it was in a full stitched episode together form. not 16 tho. nothing can fix 16
Edit: season 15 is actually on amazon prime as a full thing like 3hr 40 minutes thing and its so much better. season 16 is also there. but only 8 episodes? dont know whats that about.
