Sixteen Candles - 1984
The tag team of Molly Ringwald and John Hughs bring you this hilarious nuanced teen flick. Samantha (Ringwald) is suffering from the fact that her family completely forgot about her sixteenth birthday because her older sister, Ginny, is getting married the next day.
Sixteen Candles is one of those films that you have to see, no matter how old you are. It's filled with still relatable content, as much of the movie plot is inundated by classic teenage feelings.
