Boy, what a lousy Moby Dick! Patrick Stewart is terrific. That is it, period. The effects with the whale are fine, but when the cabin boy is drowning, the water is only up to his chest. When will the REAL Moby Dick be on DVD? Now that the Coen Brothers have paid tribute with the ending of "Oh Brother", one can get one's hopes up again. Save your money for that.

Negative

A progammable thermostat that you can actually set differently for each of the seven days - perfect for people with non traditional schedules. And the 'off the wall' setting capability makes it very convenient to set up.
