I suspect that is true for the generation that grew up in the 60’s, when comic book movies and TV shows were not existent and/or pretty god awful. For that generation, the comics books themselves were the best medium through which to enjoy the characters.
I am not sure the same can be said of those who were born in the last 20 to 30 years, when comic books themselves have comparatively gone downhill, whereas movie quality has comparatively gone way up - starting with the original superman movies, Batman movies, and then, of course, the introduction of the MCU.
but that’s just my two cents - very curious to hear what others think
