Sixteen Candles (1984)

Samantha (Molly Ringwald) is the birthday girl the film is named for, upset that she doesn't feel any different despite the coming-of-age marker having arrived, which is a trivial thing to be concerned over, I feel. Worse still, she's pissed-off that she's not the most important person at home that morning, due to her older sister getting married the following day. The words 'attention whore' spring to mind. As the day goes on we learn that she may be in love with an older guy, which is a situation that I found just as difficult to care about. One of Molly's The Breakfast Club (1985) co-stars, Anthony Michael Hall, features too, as a geek who helps her move (slightly) forward, but his ilk get mocked often, without effectively showing their individual merits.
Within John Hughes' début film are the beginnings of his lauded teen-movie credentials, but Sixteen Candles isn't a very good example of the same.
