Very interesting listening to Hals commentary track for TLJ and Hal describing Snoke as habitually an emperor clone which was recorded before any ROS revelations.
Unlike TFA v3 commentary used for TFA v4 which synces fine TLJ commentary track recorded for v2 does have syncing issues with v3 in snoke throne room battle onwards also no sound for a few minutes in places. All the same rather have this unsynced commentary track then nothing.
