I first saw this film in my teen years. I didn't understand the plot of the movie back then but found the erotic scenes interesting. I think I was also impressed by Lesters change in attitude back then.
Rewatching it in my early thirties the movie really catches me. The story of every character is catching, because everyone is struggling with different ordinary problems, some of them probably known by every adult.

* Lester is fighting with his midlifecrisis and wants to break the devils-wheel of his boring everyday life. He also hates his job and the responsibility he has to carry because of it.
* His wife Annette is frustrated by her job, because she isn't as successful as she wants to be. To bring more joy in her life she starts an affair with another (more successful) real estate salesman.
* Their daughter Jane has a lack of self-confidence. She wants to be more like her more attention-getting friend Angela.
* The neighbor Colonel Frank is militant, conservative and wants to give his values to his son. As he thinks his son is gay, he thinks it is his failure because of himself feeling attracted by men.
* The neighbors son Ricky is a survivor. He tries to mimic to be a good son to his dad to stay out of trouble with him. Because he wants the newest technology (TVs, Camcorders, etc.) he is dealing with drugs.
* Angela lies that she is sleeping with a lot of boys just to feel more self-confident when her friends geht jealous. She wants to become a model and tries to avoid to be ordinary in any way.
