The filmmaker calls this some kind of "lost classic" of the 1980s, but since it was never released back then, I'm not sure how it became a classic, if no one saw it...
There's not a lot to see here. They made some nice full-size ships and props, but the original film elements are horribly transferred, and do not mesh at all with the mid-2000 additions.
Entirely un-recommended. It's no surprise the filmmaker never made another feature.
