I have not seen every RomCom, but I have seen a lot of them.
  1. Much Ado About Nothing (1598-1599)
    (The play, although I've been told the Kenneth Branagh film version is good.)
  2. Pride and Prejudice (1813)
    The book
  3. On The Town (1944)
    The stage musical, although the movie is pretty good.
  4. Mystic Pizza (1988)
  5. When Harry Met Sally (1989)
  6. Four Weddings and a Funeral (1994)
  7. Pride and Prejudice (1995)
    The BBC Version
  8. Shakespeare in Love (1998)
  9. Notting Hill (1999)
    ...Peak Hugh Grant and peak Julia Roberts crossover...
  10. Legally Blonde (2001)
    "Oh my god! The bend and snap! Works every time!"
  11. Bridget Jones's Diary (2001)
  12. Love Actually (2003)
    I know this is controversial, and I generally pretend the Colin Firth plot line doesn't exist, but the cast is amazing and I'm weirdly attached to the very un-rom-com Emma Thompson/Alan Rickman story.
  13. Bridesmaids (2011)
  14. Hart of Dixie (2011-2012)
    Season one, specifically.
  15. In a World... (2013)
    I love that the major end-of-film win in this movie isn't actually getting the guy.
  16. Trainwreck (2015)
    Trainwreck inspired this list. I may go see it again in theaters. The last 20 minutes are perfection.
