My unpopular opinion is that Flash was perhaps one of the greatest media standards of all time. Think about it — in 2002, people were packaging entire 15 minute animations with full audio and imagery, all encapsulated in a single file that could play in any browser, for under 10mb each. Not to mention, it was one of the earliest formats to support streaming. It used vectors for art, which meant that a SWF file would look just as good today on a 4k screen as it did in 2002.

It only became awful once we started forcing it to be stuff it didn't need to be, like a Web design platform, or a common platform for applets. This introduced more and more advanced versions of scripting that continually introduced new vulnerabilities.

It was a beautiful way to spread culture back when the fastest Internet anyone could get was 1 MB/sec.
