As a Jack Griffin stan my favorite thing about the Invisible Man is how despite being overlooked in terms of spotlight from Universal the movie itself is one of the most consistantly highest rated of all the major monster movies.
Like yeah while in many ways Jack can't be made an icon in the same way as Frankenstein, Dracula or the Wolfman i'm glad people still ackowledge that despite lacking some of that iconography that makes the other monsters more recognizable that the movie itself holds up very well.
