Films so great they cannot be improved in your opinion. Not necessary your favourites (if that makes sense) or most watched, just the ones you guys think cannot be done better. Maybe not even if they were to remade at some point in the future. I'll go with
Crazy Heart- Jeff Bridges in a movie tailormade for him, acting AND singing, breaking your heart
Brokeback Mountain- another drama, great landscapes, score, honest and heartbreaking
Warrior- brother vs brother, family drama, fighting that puts everything else to shame (not a fan of wirework), great acting
