Depending on when you watched this first (or will watch it), it will determine how much impact this will have. Obviously if you've watched it back in the day, sentiment will kick in too. And while I wouldn't go as far as to say this hasn't aged well at all, there are some indicators that the impact today for some new viewers will not be the same as back then.

Having said that, the movie still holds up, as we get some missfits thrown in together and mixed up. All with different backgrounds, all with different issues and problems. All rebelling in their own way though. Against the "teacher" of course. But the authority figure here stands for more and the class struggle, the growing up struggle, the maturing struggle, the being in school struggle - all stand for something. So while you may not feel the biggest association with any of the characters, if you really dig into the movie, there is much to find here
