American Beauty was what first came to mind when I read the title. Considering what I've seen, there are some decent movies there, but probably not one I liked more.
I have seen:
Around the World in 80 Days
The Sound of Music
One Flew Over the Cuckoo's Nest
Amadeus
The Last Emperor
Rain Man
Dances With Wolves
Forrest Gump
Braveheart
American Beauty
Gladiator
Chicago
LotR: RotK
The Departed
No Country For Old Men
