I'm a videography hobbyist, there is so much discussion about aspect ratios, particularly around anamorphic lenses. In those circles, wider aspect ratio is almost always considered better (there's more to anamorphics than just aspect ratio but that's separate from this discussion). I have felt the "wider is better" idea is not so much fundamental but more learned through seeing the widescreen in movie theaters which have massive screens with a crazy sound systems. But yea, seeing the opposite argued as seeing more of the movie is pretty funny. Feels pretty arbitrary but there probably is an idea aspect ratio. Probably 16x9. haha.
