The kid is so gross looking
I spent half the movie thinking he had Down's syndrome or was a giant midget until I realized he's just a Fatboy. That is one bad haircut for him. His acting was godawful with him bumping into everything and falling around. He looks like Wee Man from Jackass
I'm convinced the reason the movie was hated so much as because this kid (and grown up JD whose acting was somehow even worse) was so unpleasant to watch. Of course if it had been the same story but about black people, it would have won multiple Oscars, gotten 100% RT score, etc.
