Authoring houses calibrate their playback equipment and generally use the same standards. White is set to 6500K (for normal TV temp) by adjusting to the appropriate levels of red/blu/grn. Brightness (black level) is set to it's lowest value without losing detail. Contrast set to it's highest level without blooming and losing white detail. Sharpness to it's lowest level without causing line detail to "ring". Color and Tint are adjusted using a blue filter to attain the best color/tint balance. A calibration disc has the appropriate test signals to set these, so you see close to what the engineer sees. Calibration allows you to get in the sweet spot where most movies will look their best.

There's always going to be bad quality movies, from either poor authoring, poor replication, poor manufacturing. Calibration will get you close enough to the standard so only minor user adjustments are needed. An ISF certified calibrator will setup your TV so "calibrated" is the default setting making it easy to return to it after making adjustment to the user controls. A disc will allow you to include the player and cable in the calibration, otherwise the calibrator would use a signal generator and calibrate the inputs to the TV.
Damn good advice and information!!!
