Emma Thompson was nominated for Best Actress in 1993 for Remains of the Day in which she is very good but it really should have been for Much Ado About Nothing, in which she is utterly radiant, the classiest and most consummate romantic comedy lead the 90s could have ever dreamt up.
The following year, the Oscars made the same mistake nominating Winona Ryder for period drama Little Women instead of the post-collegiate comedy Reality Bites, which I'd argue is her single greatest screen performance if less iconic than her star turns in Beetlejuice or Heathers.
The moral of this story: Even when they're great, comedies have such a tough time being appreciated in their time. Soon you'll be able to add Frances Ha (2013) to that infinite list of under-rewarded laughers!
