I thought the point was that Greg drew people uglier because he views them in a lowly light, not because theyβre actually ugly irl
Like I donβt think his little brother manny actually looks like that
I've always thought one of the most unintentional ways that the film assassinates Greg's character is through depicting Rowley as a totally normal-looking kid. It makes you think "ok... why did you draw your best friend like that Greg?"
