Not caricature. More like … realistic? Characters have flaws, like in the real worlds.

Like all comics like achille talon, asterix obelix, gaston lagaffe, boule et bill, cedric... Every character is exaggerated and not in flattering manner.
I had adult graphic novel from the 2000’s onward in mind.
