It's not art house, but it's certainly one of the best films that dealt with the issues of a teenager. I didn't attend a co-ed school, but a lot of the issues here still mirrored similar things we had to face. Probably outdated now, and very different to how the youth of the past few years experience life.
You know, one of those should-be boring days at school which turn out to be the best. It has the Ibsen thing, where the action takes place over 24h, heightening everything further. Bender's intensity is uncomfortable to watch but you will understand him completely - the scene where he earns himself detention upon detention is key.
30 years later what once seemed inspirational and generation defining now seems about as innocuous as today's average Disney channel flick. But once upon a time we were all that 'misunderstood' teenager; that princess; dweeb; basketcase; jock; rebel...and that's why this film still speaks to people and is so fondly remembered. Hughes left behind films that understood that. '..when you grow up your heart dies...'
When I saw The Breakfast Club at the movies back in 1985, I was as old as the actors and I liked a lot the film. Now, well now, I must've grown old unknowingly because it seems a little... dated to say the least. Recommended to film historians, though.
