The colors are crisp and vibrant and the blacks are deep and ripe. I didn't detect any unwanted noise in the picture and all of the lines are clean and detailed. Overall, it's a really great picture. The sound is also pretty sweet. There are plenty of directional effects and there are a few neat sound cues in the rear channels that will make you look around the room.
Supernova is also a special edition of sorts.
This is the extended R-rated cut, which won't matter much consider all of 5 people saw this thing in the theaters. Apparently, a lot of violence was edited out for the theatrical release and it was put back in here. It probably amounts to less than a minute, but let's give MGM props for trying. The deleted scenes are essentially elements of a darker version of the film. I can't really say what makes it darker, because that would give the ending away.
