Is there a worse aspect ratio? Literally created to scam the consumer by selling screens marketed with a certain diagonal that now have a lot less real state and are therefore cheaper to manufacture, without making the final price any lower than when it was 5:4 or even 16:10 which actually had the redeeming virtue of being essentially two 5:4 monitors together, making it ideal for twin pane work.
16:9 was sold to the consumer under the premise of it being better to consume movies in, but it's not even a properly panoramic 2.35:1. You still get black lines, but they're now smaller. Wow, what an advancement. 16:9 is a disservice to aesthetics.
