Million Dollar Baby is a great film.
The problem is, we don't know what you've seen and not seen. The best I can do is list some of the best films I've seen, and ask whether or not you've seen them:
Forrest Gump
The Lion King
City of God
Cinema Paradiso
Pi
Fight Club
Pulp Fiction
Reservoir Dogs
Oldboy
The Godfather
Casino
Goodfellas
Sin City
Twelve Angry Men
Zatoichi
Clerks
Borat
Equilibrium
The Matrix
Austin Powers
Wayne's World I & II
American Psycho
Tesis
The Machinist
Batman Begins
Ice Age
Special
3:10 to Yuma
Spirited Away
Howl's Moving Castle
....I do go on. Apologies. All good films though, or so I reckon.
