A Risky Term Rises Anew

Some imp of the perverse might have been driving me as I noticed an item on Satellite News that Rifftrax would be providing their own brand of commentary in a synch-it-yourself audio file timed to Rogue One. The odds seem minimal I'd ever listen to that track, given that Rifftrax having begun by "needling blockbusters" has kept me away from the "video files with pre-synched commentary featuring more MST3K-like B-to-Z-movies" they do mostly offer these days (although that in turn might have been an "I can't become utterly paralyzed with fear I might hear disparaging references I can't find funny" push to pledge to the MST3K revival Kickstarter). I looked at the comments, though, and one of the first ones was someone more or less saying "sure; Jyn is the Mary Sue Rey didn't turn out to be." Someone else riposted, and the comment "You don't know what a Mary Sue is" came up.
( Something came to mind at once )
