OUR PICKS

Exhibit

-- Michael O'Sullivan

Film

"American Beauty" gets America right where it lives: suburbia. Thanks to a powerful story and Kevin Spacey's performance, it's one of the best pictures of the year. See review on Page 45. -- Desson Howe

Nightlife

Comedian Dave Attell uses his angry, nearly visionary voice to scrape scathing truths from daily life's surface pleasures. His world-gone-mad rants are so powerful because they're so accurate. Catch him Friday through Sunday at the Improv (202/296-7008).

-- Eric Brace

Theater

Comedienne Margaret Cho was the first Asian-American to star in her own sitcom (ABC's "All-American Girl"), and while that made her famous it didn't make her happy. Her one-woman show "I'm the One That I Want" Friday at the Warner Theatre (202/432-7328) brings her trademark biting humor to bear on what she calls the "rise and demise" of those Hollywood days, and her life now.
