>Comic Sans, for example, was literally for speech bubbles for a comic book dog.

Comic book? I'm not sure if that's accurate terminology. It was a cartoon dog in the Microsoft Bob software.

Comic Sans might have a better reputation if its lower-case was just smaller upper-case, as Dave Gibbons does.

The problem with Comic Sans is that it was a originally a pixel font designed to look good un-antialiased at a specific pixel size. When that was expanded to a vector font, the resulting proportions looked really horrific at other sizes.

Like taking an old 16x16 NES Super Mario Bros sprite, scaling it up to 4K and expecting it to look like an attractive portrait of an Italian plumber.

Papyrus also makes for a dogshit font for legible subtitles.
