Obviously this is comedy and these flag rankings are not meant to be taken seriously, but for what it’s worth, there are clear design criteria for what makes a good flag and many on this list break them all. Like Belize. Terrible flag. Has to be one of the worst. Not sure if someone linked to it in one of the comments, but there was a TED Talk about flag design. City of Milwaukee specifically got called out for its bad flag in the TED Talk, and because of that, a contest was held for members of the public to come up with something better.
