Movie question for movie buffs?

hi, I love movies that make you want to achieve greatness in your lifetime, and move something inside of you when you see it, and I have encountered a few and REVOLUTIONARY ROAD looks good, and like one of those movies as I do not htinkt hat I want the "american dream" with kids and crap. Is it any good? is it worth seeing it? also what are some good movies that inspired you or are MUST see movies?
