Mary Shelley - "Frankenstein"
A Romantic text that criticizes 'workaholism' - not only is Victor 'alone.' deprived from social life and family, but he has also brought into being a creature (Frankenstein's monster) that is utterly unique, and 'alone,' and thus has no place in the overall great chain of being.
Christophe Gans - "Silent Hill" (2006)
A lot of people do not realize that it is a Gothic version of 'Alice in Wonderland.' This is a great film as it shows Rose's struggle alone, her husband, as well as Dahlia, the lone mother who was tricked into giving her daughter away. It also shows that even though you believe you're part of a group i.e the Religious cults, you are in actual fact alone (Postmodernism) - i.e quote "They are wolves in the skin of sheep...shepards without a flock"
Hope this helps!
Also, if you're interested, I'm holding a creative writing course at various libraries.
