This is first ever 10/10 I gave to anything on IMDb - I normally review things I like, and my average is about 7/5.
I don't think "Majority Rule" is somehow flawless; my score reflects the feeling after watching that episode. This could be descent TNG episode, easily!
It is, perhaps blunt, but on point commentary on our modern social- media controlled world. World in which hashtag activism became a valid form of social participation.
This episode doesn't focus on Mr. MacFarlane or relationship of his character with Cmdr Grayson, instead giving front seat to Lt. LeMarr with support of Grayson, Alara and Dr. Finn - giving the show proper feeling of being an ensemble endeavour - which is what Star Trek always was (with notable exception of STD).
This episode isn't extremely clever and it's not a deep philosophical debate that let us look upon ourselves through lenses of sci-fi storytelling, but it is the best a show like Orville could do, while appealing to a modern audience.
For that, it deserves, in my opinion, the highest praise and rating.
