Attempt using CORS to bypass Origin.

Did not work. Also tried using JSONP... I think I'm missing something.
Code mostly belongs to various StackOverflow and tutorials
Async Data Works Properly

I used a proxy known as corsproxy to be able to access the API of Rotten
Tomatoes without Cross Origin Error. A bit of a hack but it works!
However, there are cases by which an error occurs. I think it's due to
the fact that the proxy occasionally has slower loading period, thus the
XMLHttpRequest fails. A bit silly of me to spend all this time trying to
get it to work for this website as I'm sure that I could have hosted my
own JSON file (similarly to how corsproxy does it) and saved me a lot of
time.
