What is a Stereotype?
A stereotype is an overused, oversimplified generalisation or fixated idea about someone or something. For example, a stereotypical Australian has a bogan accent and loves to watch the football. For quite a lot of the population, that is not even true but that is how other countries think of us. Therefore, a bogan accented football lover is a stereotypical Australian.
Stereotypes in 'The Look' and 'The Fault in Our Stars'
Hazel is your stereotypical cancer patient. She does not have the brightest outlook on life although she wouldn't mind if she didn't wake up one morning. Like many other books, she falls in love with another cancer patient and he then dies, leaving her rather depressed. This same storyline can be found in other books such as My Sister's Keeper. Despite these similarities, the story does not necessarily make Hazel a stereotype although since many books and movies have a happy ending, it is quite stereotypical that she survives.
I wouldn't say that Ted is a stereotype simply because her character changes so much throughout the book. The story is predictable although the stereotype for models is that they are tall, skinny, pretty and vain. Ted in many ways is quite the opposite. Yes, she is tall and skinny although she is not exactly the prettiest girl you'll find, especially compared with her sister. Her hair and eyebrows really take away from her beauty although Sophia Bennett has chosen this path for Ted.
