It takes some getting used to, but after a viewing or two, he becomes the most interesting character in the movie after Quinlan. A very disturbing presence, that adds to Janet Leigh’s unease.
almost every main comic strip character…I mean even bill Watterson has said a few times that if "Calvin really existed and was his kid he has to strangle the little SOB fairly often "
But that’s due to the exaggerated qualities of the character whos often a mouthpiece for the creator…
I’ve always preferred Garfield. 
Assuming he got the chance.
