I feel like Marilyn looked fake, honestly. One, her hair often looks artificial blonde (unlike say, Grace Kelly), and two, the sex symbol appeal was just overdone. After seeing stuff like How to Marry a Millionaire, non-sexual comedy was much more her knack (I really think she could have ranked up there with Carol Burnett or Lucille Ball if she worked at it). Being a sex symbol will eventually fade, being able to make people laugh never will. Sadly, that's not what the studios and media wanted in her.
