Strange, I rented that movie from netflix about 2 months ago. I was always fascinated with it as a kid, now that I watched it as an adult there are some really wacked out kinda artsy fartsy references in there...still good though.
It's got several great scenes. One is the little ship playing its searchlight over the massive Cygnus, which then lights up all at once, looking like an Eiffel Tower in space. Nice design.
Another is when someone is looking through the abandoned crew quarters, finding personal effects, uniforms, all that.
But then Disney put in those robots and some horrible dialogue and bad acting. As I said, if they kept to the hardcore psychological thriller bit and Gothic Spaceship aspects, it could have been a classic.
If you want to see just some of the VFX space scenes, which are surprisingly good, someone put together a reel of just those.
