It wasn't disliked because the song was "bad". Objectively there is nothing 'bad' about the music... the external factors of overpromotion, suggested overproduction, critcism for simple composition and the response to so-called Biebermania led to said dislikes.

if you wish to talk about those factors in your presentation... cool.

if not, There is some TRULY bad music out there you can make a point with.
