The girl is just a small part of it. Lester has been trapped in a miserable job and marriage for a very long time and he just needed a reason to break free.
Before he really wasn't living his life, but just existing in a boring daily routine. his enfatuation with a teenage girl was just the trigger that caused him to take action. Suddently he became a conscious thinking individual instead of just a robot and he decided to start living his life again. So he quit his boring job, dumped his boring wife and sold his boring car.
He probably lived more in those couple of months than he would have in the next 40 years had he continued with his routine.
Besides, that teenage girl was pretty hot.

Thats like saying the dark joke at the center of the movie Alien is how much americans love their cat pets.

You missed the entire point of the movie, which is that Lester realizes what he's doing and doesn't go through with it. In his mind he had fantasized about being with her as a women. But we first see a twinge of doubt when he asks her "Do you like, Muscles?" And she nervously walks off. When she admits she's a virgin the realization hits home: She's just a kid. And he stops.

It's a movie about male menopause. If Lester had gone through with it, he'd be deplorable, but he was smart enough to realize at the end that he can't be a kid again.

You're cranky. Eat a Snickers.

She was 18!
Perfectly legal.
Only thing he did wrong really was cheating on his wife.. but she was cheating too.

You have no imagination and probably watch cartoons.

So why problem with Clinton?

Lester is an amazing character, he's a man and likes young women. You don't see people blaming Trump for that.

Nowadays, people like Angela would be "basic".

And you're very ordinary.
Screws fall out all of the time. The world's an imperfect place.

The film
Your head

we as Americans love jailbaitit's not to give you beep pervs out there a thumbs up for creaming yourselves over high schoolers on the bus
I think your Freudian Slip is you are jealous of the zeal of Lester to save himself from the American Beauty AFTER ensuring wife and brat are "happily IN it".
The give away is your word "defending" when movie does not show that he did anything to defend.

OP - it's obviously everything BUT the girl - or he would have had it off with her no questions asked. The girl is the American Beautythe film asks you to Look Closer. Advertising vs Reality.
Buy The Ticket, Take The Ride

As Americans say I think he has issues, and like Ricky should be put on Zoloft for 2 years to make him a normal mass murdering, suicidal American boy.
