Cowboy Bebop is a show that I appreciate more as I get older. It's brilliantly written, directed, designed, and scored. It seamlessly blends drama and comedy; has a cast of endearing, iconic characters; high quality (for TV) art and animation; and style in abundance. I might have to revise my score.
Even though Bebop doesn't contain as much "adult" content as some other shows, it's one of the most genuinely adult anime I've ever watched. It's one of very few shows that I wouldn't hesitate to recommend to people who aren't anime fans.
