Video

Seemingly untouched since the DVD release, the heavy, chunky grain structure suggests a master struck some time ago, and not for this modern HD era. Gains over the SD disc are fairly minimal. A slight boost in fidelity and sharpness is evident, but slight is the keyword. Most of that likely comes from the compression, which is understandably better on Blu-ray. Rough as the grain structure looks, it's at least kept organic.

Gray scale veers wide, with some fantastic highlights in the lab courtesy of the equipment. Awesome shadows achieve stable, solid black consistently. However, the gradients struggle in transitioning smoothly. Banding is lightly evident on most backgrounds, causing hard lines as gray moves between shades.

The print itself doesn't suffer any major issues. It's fairly stable, some flicker aside. An occasional speck, stray scratch, or dusty frame inhibits little. For the age (and budget), it's acceptable.

Audio

Routine PCM mono delivers the dialog clearly, nicely balanced with the score. The older analog quality delivers a general scratchiness, but it's utterly typical. Highs in the score reach stable treble. A few strums of a bass smoothly pass through the low-end.
