Heathers, Mean Girls, or Clueless?
Doesn't matter who you go with..my answer is the only acceptable one unless you include legally blonde.
Well, OBVIOUSLY Legally Blonde is better than all of them.
But think about this: Mean Girls is plagiarized Heathers. Clueless is plagiarized from Jane Austen's "Emma." Heathers is original, as far as I am aware.
And a lack of originality fills me with an overwhelming sense of ickiness.
